- Solving systems of equations using substitution/elimination
Step-by-step explanation:
<u>Step 1: Define Systems</u>
y = -7x + 6
y = -10x
<u>Step 2: Solve for </u><em><u>x</u></em>
<em>Substitution</em>
- Substitute in <em>y</em>: -10x = -7x + 6
- Add 10x to both sides: 0 = 3x + 6
- Isolate <em>x</em> term: -6 = 3x
- Isolate <em>x</em>: -2 = x
- Rewrite: x = -2
<u>Step 3: Solve for </u><em><u>y</u></em>
- Define equation: y = -10x
- Substitute in <em>x</em>: y = -10(-2)
- Multiply: y = 20
