Step-by-step explanation:
<u>Step 1: Define Systems</u>
y = 2x - 1
2x + 4y = 26
<u>Step 2: Solve for </u><em><u>x</u></em>
<em>Substitution</em>
- Substitute in <em>y</em>: 2x + 4(2x - 1) = 26
- Distribute 4: 2x + 8x - 4 = 26
- Combine like terms: 10x - 4 = 26
- [Addition Property of Equality] Add 4 on both sides: 10x = 30
- [Division Property of Equality] Divide 10 on both sides: x = 3
<u>Step 3: Solve for </u><em><u>y</u></em>
- Define equation: y = 2x - 1
- Substitute in <em>x</em>: y = 2(3) - 1
- Multiply: y = 6 - 1
- Subtract: y = 5
