- Solving systems of equations using substitution/elimination
Step-by-step explanation:
Step 1: Define Systems
4x + y = 2
y = x - 3
Step 2: Solve for x
Substitution
- Substitute in y: 4x + (x - 3) = 2
- Combine like terms: 5x - 3 = 2
- Isolate x term: 5x = 5
- Isolate x: x = 1
Step 3: Solve for y
- Define equation: y = x - 3
- Substitute in x: y = 1 - 3
- Subtract: y = -2
