Step-by-step explanation:

Step 1: Define Systems

-4x = y - 42

x = 18 + y

Step 2: Solve for y

  1. Substitute in x:                                                                                                -4(18 + y) = y - 42
  2. Distribute -4:                                                                                                   -72 - 4y = y - 42
  3. [Addition Property of Equality] Add 4y on both sides:                                 -72 = 5y - 42
  4. [Addition Property of Equality] Add 42 on both sides:                                -30 = 5y
  5. [Division Property of Equality] Divide 5 on both sides:                               -6 = y
  6. Rewrite/Rearrange:                                                                                         y = -6

Step 3: Solve for x

  1. Define original equation:                                                                               x = 18 + y
  2. Substitute in y:                                                                                                x = 18 - 6
  3. Subtract:                                                                                                           x = 12
