Step-by-step explanation:
<u>Step 1: Define Systems</u>
5x + 2y = 9
y = -x - 3
<u>Step 2: Solve for </u><em><u>x</u></em>
<em>Substitution</em>
- Substitute in <em>y</em>: 5x + 2(-x - 3) = 9
- [Distributive Property] Distribute 2: 5x - 2x - 6 = 9
- Combine like terms: 3x - 6 = 9
- [Addition Property of Equality] Add 6 on both sides: 3x = 15
- [Division Property of Equality] Divide 3 on both sides: x = 5
<u>Step 3: Solve for </u><em><u>y</u></em>
- Define original equation: y = -x - 3
- Substitute in <em>x</em>: y = -5 - 3
- Subtract: y = -8
