Solving systems of equations using substitution/elimination

Step-by-step explanation:

Step 1: Define Systems

2x + y = 3

-2x + 5y = -9

Step 2: Solve for y

Elimination

Combine equations: 6y = -6
Divide 6 on both sides: y = -1

Step 3: Solve for x

Define equation: 2x + y = 3
Substitute in y: 2x - 1 = 3
Isolate y term: 2x = 4
Isolate y: x = 2
