Introduction

In algebra, it is essential to understand the concept of equivalent expressions, which are expressions that have the same value for a given set of variables. In this article, we will explore the equivalence of two algebraic expressions, $7x + 4$ and $3x + 5 + 4x - 1$, using the values of $x=4$ and $x=6$. We will examine the truth of several statements related to the equivalence of these expressions.

The Expressions

The two algebraic expressions we will be working with are:

• $7x + 4$
• $3x + 5 + 4x - 1$

Evaluating the Expressions

To determine if these expressions are equivalent, we need to evaluate them for the given values of $x$. Let's start by substituting $x=4$ into both expressions.

Expression 1: $7x + 4$

When $x=4$, the expression becomes:

$7(4) + 4 = 28 + 4 = 32$

Expression 2: $3x + 5 + 4x - 1$

When $x=4$, the expression becomes:

$3(4) + 5 + 4(4) - 1 = 12 + 5 + 16 - 1 = 32$

As we can see, both expressions evaluate to the same value, $32$, when $x=4$. This suggests that the expressions may be equivalent.

Evaluating the Expressions for $x=6$

Now, let's substitute $x=6$ into both expressions.

Expression 1: $7x + 4$

When $x=6$, the expression becomes:

$7(6) + 4 = 42 + 4 = 46$

Expression 2: $3x + 5 + 4x - 1$

When $x=6$, the expression becomes:

$3(6) + 5 + 4(6) - 1 = 18 + 5 + 24 - 1 = 46$

Again, both expressions evaluate to the same value, $46$, when $x=6$. This further supports the idea that the expressions are equivalent.

Analyzing the Statements

Now that we have evaluated the expressions for the given values of $x$, let's examine the truth of the following statements:

• When $x=4$, the expressions $7x + 4$ and $3x + 5 + 4x - 1$ are equivalent.
• When $x=6$, the expressions $7x + 4$ and $3x + 5 + 4x - 1$ are equivalent.
• The expressions $7x + 4$ and $3x + 5 + 4x - 1$ are equivalent for all values of $x$.
• The expressions $7x + 4$ and $3x + 5 + 4x - 1$ are not equivalent for any value of $x$.

Conclusion

Based on our evaluation of the expressions for the given values of $x$, we can conclude that:

• When $x=4$, the expressions $7x + 4$ and $3x + 5 + 4x - 1$ are equivalent.
• When $x=6$, the expressions $7x + 4$ and $3x + 5 + 4x - 1$ are equivalent.

However, we cannot conclude that the expressions are equivalent for all values of $x$. To determine if the expressions are equivalent for all values of $x$, we would need to evaluate them for an infinite number of values, which is not feasible.

Therefore, the correct statements are:

• When $x=4$, the expressions $7x + 4$ and $3x + 5 + 4x - 1$ are equivalent.
• When $x=6$, the expressions $7x + 4$ and $3x + 5 + 4x - 1$ are equivalent.

Final Thoughts

In conclusion, the expressions $7x + 4$ and $3x + 5 + 4x - 1$ are equivalent for the given values of $x$, but we cannot conclude that they are equivalent for all values of $x$. This highlights the importance of carefully evaluating algebraic expressions and considering the limitations of our conclusions.

  Frequently Asked Questions (FAQs) =====================================

Q: What are equivalent expressions in algebra?

A: Equivalent expressions in algebra are expressions that have the same value for a given set of variables. In other words, they are expressions that are equal to each other, but may be written in different ways.

Q: How do I determine if two expressions are equivalent?

A: To determine if two expressions are equivalent, you can substitute values for the variables and evaluate both expressions. If the expressions have the same value for the given values, then they are likely equivalent.

Q: What are some common ways to simplify algebraic expressions?

A: Some common ways to simplify algebraic expressions include:

• Combining like terms
• Factoring out common factors
• Canceling out common factors
• Using the distributive property

Q: Can I use the values of x=4 and x=6 to determine if two expressions are equivalent for all values of x?

A: No, using the values of x=4 and x=6 is not enough to determine if two expressions are equivalent for all values of x. You would need to evaluate the expressions for an infinite number of values to be certain that they are equivalent for all values of x.

Q: How do I know if an expression is equivalent to another expression?

A: To determine if an expression is equivalent to another expression, you can use the following steps:

1. Simplify both expressions as much as possible.
2. Compare the simplified expressions to see if they are the same.
3. If the expressions are the same, then they are equivalent.

Q: Can I use the distributive property to simplify an expression?

A: Yes, you can use the distributive property to simplify an expression. The distributive property states that for any numbers a, b, and c:

a(b + c) = ab + ac

You can use this property to simplify expressions by distributing the terms inside the parentheses.

Q: How do I factor out common factors from an expression?

A: To factor out common factors from an expression, you can follow these steps:

1. Identify the common factors in the expression.

3. Simplify the expression as much as possible.

Q: Can I cancel out common factors from an expression?

A: Yes, you can cancel out common factors from an expression. However, you can only cancel out common factors that appear in both the numerator and the denominator.

Q: How do I use the distributive property to simplify an expression?

A: To use the distributive property to simplify an expression, you can follow these steps:
