Understanding Algebraic Expressions

Algebraic expressions are a fundamental concept in mathematics, and simplifying them is a crucial skill to master. In this article, we will explore how to simplify algebraic expressions, with a focus on the given problem: 4x−2y−x+5y−84x - 2y - x + 5y - 8. We will break down the steps involved in simplifying this expression and identify the coefficient of the xx-term in the fully simplified expression.

Step 1: Combine Like Terms

The first step in simplifying an algebraic expression is to combine like terms. Like terms are terms that have the same variable raised to the same power. In the given expression, we have two terms with the variable xx: 4x4x and −x-x. We can combine these two terms by adding their coefficients.

Combining Coefficients

The coefficient of a term is the numerical value that multiplies the variable. In the case of the xx-term, the coefficient is 4. When we combine the two xx-terms, we add their coefficients: 4+(−1)=34 + (-1) = 3. Therefore, the simplified expression for the xx-term is 3x3x.

Step 2: Simplify the Constant Term

In addition to combining like terms, we also need to simplify the constant term. The constant term is the term that does not have a variable. In the given expression, the constant term is −8-8. We can simplify this term by combining it with any other constant terms.

Simplifying the Constant Term

In this case, there are no other constant terms to combine with the −8-8 term. Therefore, the simplified expression for the constant term is still −8-8.

Step 3: Write the Fully Simplified Expression

Now that we have combined like terms and simplified the constant term, we can write the fully simplified expression. The fully simplified expression is obtained by combining all the simplified terms.

Fully Simplified Expression

The fully simplified expression is 3x+5y−83x + 5y - 8.

Identifying the Coefficient of the xx-Term

The coefficient of the xx-term is the numerical value that multiplies the variable xx. In the fully simplified expression, the coefficient of the xx-term is 3.

Conclusion

In conclusion, simplifying algebraic expressions is a crucial skill to master in mathematics. By following the steps outlined in this article, we can simplify complex expressions and identify the coefficients of the variables. In the given problem, we simplified the expression 4x−2y−x+5y−84x - 2y - x + 5y - 8 and identified the coefficient of the xx-term as 3.

Final Answer

The final answer is 3\boxed{3}.
