### What is the Value of X if 2x - 9 = 9?

If you are trying to solve a math equation and you are stuck on a certain step, it can be very frustrating. In this article, we will discuss the equation 2x - 9 = 9 and how to solve for x. We will also discuss some related topics and provide examples to help you better understand the concept.

• The equation 2x - 9 = 9 is a linear equation.

• To solve for x, we need to isolate the variable on one side of the equation.

• Adding 9 to both sides of the equation gives us 2x = 18.

• Dividing both sides of the equation by 2 gives us x = 9.

• This same method can be used to solve other types of equations as well.

The equation 2x - 9 = 9 is a linear equation. A linear equation is an equation that can be written in the form ax + b = c, where a, b, and c are constants and x is a variable. In this equation, a is equal to 2, b is equal to -9, and c is equal to 9. To solve for x, we need to isolate the variable on one side of the equation. To do this, we can add 9 to both sides of the equation.

Adding 9 to both sides of the equation gives us 2x = 18. To isolate the variable, we need to divide both sides of the equation by 2. Dividing both sides of the equation by 2 gives us x = 9. Therefore, the value of x in the equation 2x - 9 = 9 is 9.

In addition to solving linear equations, this same method can be used to solve other types of equations as well. For example, if we have the equation 3x + 4 = 10, we can use the same method to solve for x. First, we add 4 to both sides of the equation to get 3x = 14. Then, we divide both sides of the equation by 3 to get x = 4.5. Therefore, the value of x in the equation 3x + 4 = 10 is 4.5.

Good to know:

• Linear Equation: An equation that can be written in the form ax + b = c, where a, b, and c are constants and x is a variable.

• Variable: A symbol, usually an alphabet, used to represent a number in an equation.

In conclusion, the equation 2x - 9 = 9 can be solved by adding 9 to both sides of the equation and then dividing both sides of the equation by 2. The value of x in this equation is 9. This same method can be used to solve other types of equations as well.
