General Formulas and Concepts:

  • Order of Operations: BPEMDAS

Step-by-step explanation:

Step 1: Define equation

(180 - x) + (90 - x) = 124

Step 2: Solve for x

  1. Combine like terms:                         270 - 2x = 124
  2. Subtract 270 on both sides:            -2x = -146
  3. Divide -2 on both sides:                   x = 73

Step 3: Check

Plug in x to verify it's a solution.

  1. Substitute:                         (180 - 73) + (90 - 73) = 124
  2. Subtract:                            107 + 17 = 124
  3. Add:                                   124 = 124
