Question

Is 8 a solution to 3(x + 1) = 4x + 8? Show all work for full credit.

Answer 1

no

Explanation:

3* (X +1)= 4*X + 8

3x + 3 =4x + 8

4x- 3 X = 3 - 8

X= -5

Answer 2

Answer: No, see below for more.

Explanation:

Given:

3(x + 1) = 4x + 8

Distribute:

3x + 3 = 4x + 8

Subtract 4x from both sides of the equation:

-1x + 3 = 8

Subtract 3 from both sides of the equation:

-1x = 5

Divide both sides of the equation by -1.

x = -5

No, 5 ≠ 8, so 8 is not a solution.
