Answer:

x = -7

General Formulas and Concepts:

Pre-Algebra

  • Order of Operations: BPEMDAS
  • Equality Properties

Explanation:

Step 1: Define equation

2.5x + 10 = x - 0.5

Step 2: Solve for x

  1. Subtract x on both sides: 1.5x + 10 = -0.5
  2. Subtract 10 on both sides: 1.5x = -10.5
  3. Divide both sides by 1.5: x = -7

Step 3: Check

Plug in x to verify it's a solution.

  1. Substitute: 2.5(-7) + 10 = -7 - 0.5
  2. Multiply: -17.5 + 10 = -7 - 0.5
  3. Add/Subtract: -7.5 = -7.5

And we have our answer!
