Step-by-step 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
