General Formulas and Concepts:
Pre-Algebra
- Order of Operations: BPEMDAS
- Equality Properties
Step-by-step explanation:
Step 1: Define equation
-2(x - 4) = -16
Step 2: Solve for x
- Distribute -2: -2x + 8 = -16
- Isolate x term: -2x = -24
- Isolate x: x = 12
Step 3: Check
Plug in x to verify it's a solution.
- Substitute: -2(12 - 4) = -16
- Subtract: -2(8) = -16
- Multiply: -16 = -16
Here we see that -16 does indeed equal -16.
∴ x = 12 is a solution of the equation.
