Answer:

  x = -6

Step-by-step explanation:

Subtract the right side, simplify, divide by the x-coefficient.

  4(x -3) +54 +3x = 0

  4x -12 +54 +3x = 0 . . . . eliminate parentheses

  7x +42 = 0 . . . . . . . . . . combine terms

  x +6 = 0 . . . . . . . . . . . . . divide by 7

  x = -6 . . . . . . . . . . . . . . . add the opposite of the constant
