- Solving systems of equations using substitution/elimination
Step-by-step explanation:
Step 1: Define Systems
y = x - 4
y = 4x + 2
Step 2: Solve for x
Substitution
- Substitute in y: x - 4 = 4x + 2
- Isolate x terms: -4 = 4x + 2
- Isolate x term: -6 = 4x
- Isolate x: -3/2 = x
- Rewrite: x = -3/2
Step 3: Solve for y
- Define equation: y = x - 4
- Substitute in x: y = -3/2 - 4
- Subtract: y = -11/2
Answer by Khan Academy:
x=−2
y=−6
