Solve the following: 2x - 2 = 4x + 6

olchik [2.2K]

Answer:

x = -4

Step-by-step explanation:

Step 1: Subtract 2x from both sides

2x - 2 - 2x = 4x + 6 - 2x

-2 = 2x + 6

Step 2: Subtract 6 from both sides

-2 - 6 = 2x + 6 - 6

-8 = 2x

Step 3: Divide both sides by 2

-8 / 2 = 2x / 2

-4 = x

Answer: x = -4
