General Formulas and Concepts:

Pre-Algebra

• Order of Operations: BPEMDAS
• Equality Properties

Step-by-step 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!
