Answer:

(1) 6x + 3 = 15

(2) x = 2

Explanation:

  • We have the equation
    9x + 3 = 3x + 15
  • Subtract 3x from both sides to get rid of the 3x on the right:
    9x - 3x + 3 = 3x - 3x + 15
    → 6x + 3 = 0 + 15
    6x + 3 = 15
  • Subtract 3 from both sides:
    6x + 3 - 3 = 15 - 3
    6x = 12
  • Divide both sides by 6:
    6x/6 = 12/6
    x = 2
