General Formulas and Concepts:
<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
- Equality Properties
<u>Algebra I</u>
- Solving systems of equations using substitution/elimination
Step-by-step explanation:
<u>Step 1: Define systems</u>
7x + 3y = 12
7x - 3y = 30
<u>Step 2: Solve for </u><em><u>x</u></em>
- Eliminate <em>y</em>: 14x = 42
- Isolate <em>x</em>: x = 3
<u>Step 3: Solve for </u><em><u>y</u></em>
- Substitute in <em>x</em>: 7(3) + 3y = 12
- Multiply: 21 + 3y = 12
- Isolate <em>y</em> term: 3y = -9
- Isolate <em>y</em>: y = -3
And we have our final answer!
