Answer:

x = 14

Explanation:

In this problem, we must isolate x

  1. Given: -2(x - 2) = - 3 - 21
  2. Simplify the right side: -2(x - 2)= - 24
  3. Distribute the -2 to x and -2 (multiply): -2x + 4 = -24
  4. Subtract 4 from both sides: -2x = -28
  5. Divide both sides by -2: x = 14

Answer:

x = 14

Explanation:

you would first distribute the -2 with x - 2, which should give you -2x + 4, and you want to do the -3 - 21, which would give you -24, then subtract 4 from -2x + 4, then you should have -2x = -28, then divide it by -2, which should give you x = 14
