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
