Answer:

All real numbers are solutions.

Step-by-step explanation:

Let's solve your equation step-by-step.

−28+4x=4(x−7)

Step 1: Simplify both sides of the equation.

−28+4x=4(x−7)

−28+4x=(4)(x)+(4)(−7)(Distribute)

−28+4x=4x+−28

4x−28=4x−28

Step 2: Subtract 4x from both sides.

4x−28−4x=4x−28−4x

−28=−28

Step 3: Add 28 to both sides.

−28+28=−28+28

0=0

Answer:

All real numbers are solutions.
