Answer:

2 and 4 6/7

Step-by-step explanation:

  • - |12 - 3.5x| = -5        ⇒ cancelling negative signs
  • |12 - 3.5x| = 5
  • 12 - 3.5x = ± 5          ⇒ getting rid of absolute

1. First equation

  • 12 -3.5x = 5
  • 3.5x = 12 -5
  • 3.5x = 7
  • x = 7/3.5
  • x= 2

2. Second equation

  • 12 - 3.5x = -5
  • 3.5x = 12 +5
  • 3.5x = 17
  • x= 17/3.5
  • x= 34/7
  • x= 4 6/7
