Step-by-step explanation:
Let's solve your equation step-by-step.
8x−6=2x−6+6x
Step 1: Simplify both sides of the equation.
8x−6=2x−6+6x
8x+−6=2x+−6+6x
8x−6=(2x+6x)+(−6)(Combine Like Terms)
8x−6=8x+−6
8x−6=8x−6
Step 2: Subtract 8x from both sides.
8x−6−8x=8x−6−8x
−6=−6
Step 3: Add 6 to both sides.
−6+6=−6+6
0=0
