General Formulas and Concepts:
Pre-Algebra
- Order of Operations: BPEMDAS
- Equality Properties
Explanation:
Step 1: Define equation
0.75h + 3 = 12
Step 2: Solve for h
- Subtract 3 on both sides: 0.75h = 9
- Divide 0.75 on both sides: h = 12
Step 3: Check
Plug in h into the original equation to verify it's a solution.
- Substitute in h: 0.75(12) + 3 = 12
- Multiply: 9 + 3 = 12
- Add: 12 = 12
Here we see that 12 does indeed equal 12.
∴ h = 12 is a solution of the equation.
