• Solving systems of equations using substitution/elimination

Explanation:

Step 1: Define Systems

x - y = -2

3x - y = 2

Step 2: Rewrite Systems

x - y = 2

1. Add y to both sides: x = 2 + y

Step 3: Redefine Systems

x = 2 + y

3x - y = 2

Step 4: Solve for y

Substitution

1. Substitute in x: 3(2 + y) - y = 2
2. Distribute 3: 6 + 3y - y = 2
3. Combine like terms: 6 + 2y = 2
4. Isolate y term: 2y = -4
5. Isolate y: y = -2

Step 5: Solve for x

1. Define: x - y = 2
2. Substitute in y: x - (-2) = 2
3. Simplify: x + 2 = 2
4. Isolate x: x = 0
