Answer 1

Answer:

x=0

Step-by-step explanation:

look at the pictures I sent for an explanation how to do it.

Answer 2

Answer:

part A) x=0

part B) see the explanation

Step-by-step explanation:

Part A) Solve the equation

5 + x - 12 = 2x - 7

solve for x

x - 7 = 2x - 7

Combine like terms left side

Adds 7 both sides

x = 2x

subtract x both sides

x = 0

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

5 + (-0.5) - 12 = 2 (-0.5) - 7

-7.5> -8

For x=0

substitute in the given equation

5 + (0) - 12 = 2(0) - 7

For x=1

substitute in the given equation

5 + (1) - 12 = 2(1) - 7

-6 < -5

mark me brainly list please :)
