Don't miss that second to last one. I did it wrong. It was "Subtraction property of equality."

1.) 6x-8y=18, 2x+8y=6 → Multiplication property of equality

2.) 8x=24 → Addition property of equality

3.) x=3 → Division property of equality

4.) 3(3)-4y=9 → Substitution property of equality

5.) 9-4y=9 → Simplify

6.) -4y=0 → Subtraction property of equality

7.) y=0 → Division property of equality
