Explanation:

Step 1: Define Systems

x + y - 6 = 0

x - y = 0

Step 2: Rewrite Systems

x + y - 6 = 0

1. Add 6 on both sides: x + y = 6

Step 3: Redefine Systems

x + y = 6

x - y = 0

Step 4: Solve for x

Elimination

1. Combine 2 equations: 2x = 6
2. Divide 2 on both sides: x = 3

Step 5: Solve for y

1. Define equation: x - y = 0
2. Substitute in x: 3 - y = 0
3. Subtract 3 on both sides: -y = -3
4. Divide -1 on both sides: y = 3
