One of Coach Hopkins' students made a mistake when solving the equation below and got x=2 as their solution. What mistake did they most likely make?

4x - 12 = 20

• They mistakenly subtracted 12 from both sides instead of adding 12 to both sides.

• They mistakenly multiplied both sides of the equation by 4.

• They mistakenly subtracted 20 from both sides.

• They mistakenly divided both sides of the equation by 4 before adding 12 to both sides.

Solve for x.

6x - 12 = 4x + 28

• x = 14

• x = 26

• x =20

• x = 10

Combine ALL the "Like Terms" in other words, simplify the expression.

12w + 3x + 8y - 20w - 8x + 2y - 14 + 20

• -8w + 5y - 10x + 6

• -8w - 5x + 10y + 6

• 12w - 5x + 10y + 20

• -8w - 5x + 8y + 2y + 6
