Can somebody help me... I need to know how to do 2x - 8 = 16
2x - 8 = 16
2x - 8 + 8 = 16 + 8
2x = 24
x = 24/2
x = 12
thanks for your help ms.sue .
You're welcome, Jennifer.
Of course! I can help you solve the equation 2x - 8 = 16.
To solve this equation, we need to isolate the variable x. Here are the steps to follow:
Step 1: Add 8 to both sides of the equation to get rid of the constant term on the left side:
2x - 8 + 8 = 16 + 8
2x = 24
Step 2: Divide both sides of the equation by 2 to solve for x:
2x / 2 = 24 / 2
x = 12
So, the solution to 2x - 8 = 16 is x = 12.
By adding 8 to both sides of the equation and then dividing both sides by 2, we isolated the variable x and determined its value. This is a basic example of solving a linear equation.
