Question

Solve the equation for x
3x - 3 + x = - (x - 12)

Answer 1

x = 3

Explanation:

Solve the equation for x

3x - 3 + x = - (x - 12)

3x - 3 + x - (x - 12) = 0

5x - 15 = 0

x = -(-15)/5

x = 3

------------------------

check

3 * 3 - 3 + 3 = -(3 - 12)

9 - 3 + 3 = 9

9 = 9

the answer is good
