Answer:

  • x = 7

Step-by-step explanation:

Testing if 6 is the solution:

  • 5(x – 3) = x + 13
  • 5(6 - 3) ? 6 + 13
  • 5(3) ? 19
  • 15 ≠ 19

6 is not a solution

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

Solving for x:

  • 5(x – 3) = x + 13            ⇒ open parenthesis
  • 5x - 15 = x + 13              ⇒ isolate variable
  • 5x - x = 13 + 15              ⇒ simplify
  • 4x = 28                          
  • x = 28/4
  • x = 7
