Given the equation 5 + x -12 = 2x - 7.

Part A. Solve the equation 5 + x - 12 = 2x - 7. In your final answer, be sure to state the solution and include all of your work.

Part B. Use the values x = -0.5,0,1 to prove your solution to the equation 5 + x - 12 = 2x - 7 . In your final answer, include all of your calculations.

part A) x=0

part B) see the explanation

Step-by-step explanation:

Part A) Solve the equation

we have

solve for x

Combine like terms left side

Adds 7 both sides

subtract x both sides

Part B) Use the values x = -0.5,0,1 to prove your solution to the given equation

For x=-0.5

substitute in the given equation

For x=0

substitute in the given equation

For x=1

substitute in the given equation

the answer to your question is b.
