General Formulas and Concepts:

Order of Operations: BPEMDAS

Step-by-step explanation:

Step 1: Define

-1x = -8 - 2x

Step 2: Solve for x

  1. Simplify:                                 -x = -8 - 2x
  2. Add 2x on both sides:          x = -8

Step 3: Check

Plug in x to verify it's a solution.

  1. Substitute:                         -1(-8) = -8 - 2(-8)
  2. Multiply:                             8 = -8 + 16
  3. Add:                                   8 = 8
