Answer:

Below!

Explanation:

Let's simplify the equation.

  • => a(4 - x) = -3x + b
  • => 4x - ax = -3x + b
  • => 4x + 3x - ax = b
  • => 7x - ax = b
  • => 7x - (12)x = 25 (Replacing a = 12; b = 25)
  • => -5x = 25
  • => x = -5

The 'a' value must be in the negatives, while the 'b' value must be in the positives. To make it equal, use the given clue 'x = -5'.
