Introduction

Solving for x in a linear equation can be a daunting task, especially when dealing with fractions and negative numbers. However, with a clear understanding of the steps involved and a bit of practice, you can become proficient in simplifying even the most complex equations. In this article, we will walk you through the process of solving for x in the equation x+19−6=−6\frac{x+19}{-6} = -6.

Understanding the Equation

Before we dive into the solution, let's take a closer look at the equation and understand what it's asking for. The equation is x+19−6=−6\frac{x+19}{-6} = -6, where x is the variable we need to solve for. The equation is a linear equation, meaning it can be represented as a straight line on a graph. Our goal is to isolate x and find its value.

Step 1: Multiply Both Sides by -6

To solve for x, we need to get rid of the fraction. One way to do this is to multiply both sides of the equation by -6. This will eliminate the fraction and allow us to work with whole numbers.

\frac{x+19}{-6} = -6
\Rightarrow (x+19) = -6 \times -6
\Rightarrow (x+19) = 36

Step 2: Subtract 19 from Both Sides

Now that we have eliminated the fraction, we can focus on isolating x. To do this, we need to get rid of the +19 on the left-hand side of the equation. We can do this by subtracting 19 from both sides of the equation.

(x+19) = 36
\Rightarrow x+19-19 = 36-19
\Rightarrow x = 17

Conclusion

And there you have it! By following the steps outlined above, we have successfully solved for x in the equation x+19−6=−6\frac{x+19}{-6} = -6. The value of x is 17. Remember, solving for x in a linear equation can be a straightforward process if you take it one step at a time. With practice and patience, you'll become a pro at simplifying even the most complex equations.

Introduction

Solving for x in a linear equation can be a challenging task, especially for those who are new to algebra. However, with practice and patience, you can become proficient in simplifying even the most complex equations. In this article, we will answer some of the most frequently asked questions about solving for x in a linear equation.

Q: What is a linear equation?

A: A linear equation is an equation in which the highest power of the variable (x) is 1. It can be represented as a straight line on a graph. Examples of linear equations include 2x + 3 = 5 and x - 2 = 3.

Q: How do I solve for x in a linear equation?

A: To solve for x in a linear equation, you need to isolate the variable (x) on one side of the equation. This can be done by adding, subtracting, multiplying, or dividing both sides of the equation by the same value.

Q: What is the order of operations when solving for x?

A: When solving for x, you should follow the order of operations (PEMDAS):

  1. Parentheses: Evaluate any expressions inside parentheses first.
  2. Exponents: Evaluate any exponential expressions next.
  3. Multiplication and Division: Evaluate any multiplication and division operations from left to right.
  4. Addition and Subtraction: Finally, evaluate any addition and subtraction operations from left to right.

Q: How do I deal with fractions in a linear equation?

A: When dealing with fractions in a linear equation, you can eliminate them by multiplying both sides of the equation by the denominator. For example, if you have the equation x+19−6=−6\frac{x+19}{-6} = -6, you can multiply both sides by -6 to eliminate the fraction.

Q: What is the difference between a linear equation and a quadratic equation?

A: A linear equation is an equation in which the highest power of the variable (x) is 1. A quadratic equation, on the other hand, is an equation in which the highest power of the variable (x) is 2. Examples of quadratic equations include x^2 + 4x + 4 = 0 and x^2 - 3x - 4 = 0.

Q: How do I solve for x in a quadratic equation?

A: To solve for x in a quadratic equation, you can use the quadratic formula: x = (-b ± √(b^2 - 4ac)) / 2a. This formula can be used to find the solutions to a quadratic equation.

Q: What are some common mistakes to avoid when solving for x?

A: Some common mistakes to avoid when solving for x include:

  • Forgetting to multiply both sides of the equation by the denominator when dealing with fractions.
  • Not following the order of operations (PEMDAS).
  • Not isolating the variable (x) on one side of the equation.
  • Making errors when adding, subtracting, multiplying, or dividing both sides of the equation.

Q: How can I practice solving for x?

A: You can practice solving for x by working through examples and exercises in a textbook or online resource. You can also try solving for x in real-world problems, such as calculating the cost of an item or determining the distance between two points.

Q: What are some real-world applications of solving for x?

A: Solving for x has many real-world applications, including:

  • Calculating the cost of an item or service.
  • Determining the distance between two points.
  • Finding the area or perimeter of a shape.
  • Solving problems in physics, engineering, and other fields.
