Final answer:

To solve the equations for x, we need to isolate x on one side of the equation. For each equation, we perform the necessary operations to get x by itself. The solutions for x are x = 3/a, x = -6/a.

Step-by-step explanation:

  1. For equation 1: 7 + 2ax = 13
  2. Subtract 7 from both sides: 2ax = 6
  3. Divide both sides by 2a: x = 3/a
  4. For equation 2: -ax - 20 = -14
  5. Add 20 to both sides: -ax = 6
  6. Divide both sides by -a: x = -6/a
  7. For equation 3: 4 = 6/(ax) + 5
  8. Subtract 5 from both sides: -1 = 6/(ax)
  9. Flip the fraction and multiply both sides by (ax): -ax = 6
  10. Divide both sides by -a: x = -6/a

The solutions for x are: x = 3/a, x = -6/a
