General Formulas and Concepts:
<u>Pre-Alg</u>
- Order of Operations: BPEMDAS
- Equality Properties
Step-by-step explanation:
<u>Step 1: Define equation</u>
12 = 5/2b
<u>Step 2: Solve for </u><em><u>b</u></em>
- Rewrite: 5/2b = 12
- Divide both sides by 5/2: b = 24/5
<u>Step 3: Check</u>
<em>Plug in b to verify it's a solution.</em>
- Substitute: 12 = 5/2(24/5)
- Multiply: 12 = 12
