Answer:

  1. c = 22 (= -18)
  2. c = 23 (< -18 because - goes down).
  3. 4 - c ≤ -18

Step-by-step explanation:

Solve for 1st answer:

  • 4 - c = -18
  • = 4 - 22 = -18
  • = 0 - 18 = -18 (Basically subtract 4 from 22)
  • = -18
  • c = 22

Solve for 2nd answer:

  • 4 - c < -18
  • = 4 - 23 < -18
  • = 0 - 19 < -18
  • = -19
  • c = 23

Actual answer:

  • 4 - c ≤ -18.
