  • Left to Right

Equality Properties

  • Multiplication Property of Equality
  • Division Property of Equality
  • Addition Property of Equality
  • Subtract Property of Equality

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
