- Solving systems of equations using substitution/elimination
Step-by-step explanation:
<u>Step 1: Define Systems</u>
15s + t = 5
4s = 3t + 34
<u>Step 2: Rewrite</u>
15s + t = 5
- Subtract <em>t</em> on both sides: 15s = -t + 5
- Multiply both sides by 3: 45s = -3t + 15
<u>Step 3: Redefine Systems</u>
45s = -3t + 15
4s = 3t + 34
<u>Step 4: Solve for </u><em><u>s</u></em>
<em>Elimination</em>
- Combine equations: 49s = 49
- Divide 49 on both sides: s = 1
<u>Step 5: Solve for </u><em><u>t</u></em>
- Define equation: 15s + t = 5
- Substitute in <em>s</em>: 15(1) + t = 5
- Multiply: 15 + t = 5
- Isolate <em>t</em>: t = -10
