- Solving systems of equations using substitution/elimination
Step-by-step explanation:
<u>Step 1: Define Systems</u>
4x + y = 42
y = x + 7
<u>Step 2: Solve for </u><em><u>x</u></em>
<em>Substitution</em>
- Substitute in <em>y</em>: 4x + (x + 7) = 42
- Combine like terms: 5x + 7 = 42
- Isolate <em>x</em> term: 5x = 35
- Isolate <em>x</em>: x = 7
<u>Step 3: Solve for </u><em><u>y</u></em>
- Define equation: y = x + 7
- Substitute in <em>x</em>: y = 7 + 7
- Add: y = 14
