<u>Algebra I</u>
- Solving systems of equations using substitution/elimination
Step-by-step explanation:
<u>Step 1: Define Systems</u>
-2x - y = 0
10x + y = -8
<u>Step 2: Solve for </u><em><u>x</u></em>
<em>Elimination</em>
- Combine equations: 8x = -8
- Isolate <em>x</em>: x = -1
<u>Step 3: Solve for </u><em><u>y</u></em>
- Define equation: -2x - y = 0
- Substitute in <em>x</em>: -2(-1) - y = 0
- Multiply: 2 - y = 0
- Isolate <em>y</em> term: -y = -2
- Isolate <em>y</em>: y = 2
