- Solving systems of equations using substitution/elimination
Step-by-step explanation:
Step 1: Define Systems
3x + y = 10
y = x + 2
Step 2: Solve for x
Substitution
- Substitute in y: 3x + (x + 2) = 10
- Combine like terms: 4x + 2 = 10
- Isolate x term: 4x = 8
- Isolate x: x = 2
Step 3: Solve for y
- Define equation: y = x + 2
- Substitute in y: y = 2 + 2
- Add: y = 4
