Plug in 12 for y and rewrite the equation.
12 = 4x + 4
Subtract 4 from both sides.
8 = 4x
Divide by 4 on both sides.
2 = x
The ordered pair is (2, 12) and x = 2.

General Formulas and Concepts:
<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
- Equality Properties
Step-by-step explanation:
<u>Step 1: Define equation</u>
0.8x = 7.2
<u>Step 2: Solve for </u><em><u>x</u></em>
- Divide both sides by 0.8: x = 9
<u>Step 3: Check</u>
<em>Plug in x to verify it's a solution.</em>
- Substitute: 0.8(9) = 7.2
- Multiply: 7.2 = 7.2
7.2 does indeed equal 7.2. ∴ x = 9 is a solution.
And we have our final answer!
