Step-by-step explanation:

Step 1: Define

Identify.

-1.2(3 - x) = -1.8

Step 2: Solve for x

  1. (Parenthesis) Distribute -1.2 [Distributive Property]:                                       -3.6 + 1.2x = -1.8
  2. [Addition Property of Equality] Add 3.6 on both sides:                                 1.2x = 1.8
  3. [Division Property of Equality] Divide 1.2 on both sides:                              x = 1.5
