Question

How to solve x in a step by step response

Answer 1

Step 1: Simplify both sides of the equation.x2−7=9Simplify: (Show steps)12x−7=9Step 2: Add 7 to both sides.12x−7+7=9+712x=16Step 3: Multiply both sides by 2.2*(12x)=(2)*(16)x=32

Answer 2

x/2 - 7=9
Add 7 to both sides so that it cancels out the -7
x/2= 16
Multiply both sides by 2 so that the only thing remaining on the left side is the variable x.
Final Answer: x=32
