Subtraction Property of Equality
Division Property of Equality

Answer 2

Answer and Step-by-step explanation:

Since we have given that

`2x-4y=18\\\\3x+3y=0`

We need to mention the properties for the given steps:

`6x-12=54\\\\6x+6y=0`

1) Multiplication property of equality

`-18y=54`

2) Addition property of equality

`y=-3`

3) Division property of equality

`2x-4(-3)=18`

4) Substitution property of equality

2x+12=18

5) Simplify

2x=6

6) Subtraction property of equality

x=3

7) Division property of equality
