Question

Which value of x makes the following equation true?
3(x-3) = -2x + 31

Answer 1

x=8

Explanation:

1. Distribute the 3 into the (x-3) to have 3x-9 = -2x+31

2. Add 9 to each side to get 3x = -2x+40

3. Add 2x to each side to get 5x = 40

4. Divide each side by 5 to get x=8

Answer 2

Solving for the value of x,

→ 3(x - 3) = -2x + 31

→ 3x - 9 = -2x + 31

→ 3x + 2x = 31 + 9

→ 5x = 40

→ x = 40/5

→ [ x = 8 ]

Thus, the value of x is 8.
