Answer:

Solve for x and justify each step with a reason: 3(x - 2) + 5x = 9x - 24

Steps:

Justification (Reasons):

3(x - 2) + 5x = 9x - 24

Given

3x - 6 + 5x = 9x - 24

Distributive Property

3x + 5x - 6 = 9x - 24

Commutative Property of Addition

8x - 6 = 9x - 24

Combine Like Terms

8x - 8x - 6 = 9x - 8x - 24

Subtraction Property of Equality

0 - 6 = x - 24

Additive Inverse Property (left)

Combine Like Terms (right)

-6 = x - 24

Additive Identity Property

-6 + 24 = x - 24 + 24

Addition Property of Equality

18 = x + 0

Addition (left)

Additive Inverse Property (right)

18 = x

Additive Identity Property
