Answer 2

-5x-3y-9=0

4x-18y-54=0

6(-5x-3y-9)=0

-30x-18y-54=0

(-30x-18y-54) - (4x-18y-54)=0

-30x-18y-54-4x+18y+54=0

-30x-4x-18y+18y-54+54=0

-34x+0+0=0

-34x=0

x=0/(-34)

x=0

-5x-3y-9=0

-5(0)-3y-9=0

-0-3y-9=0

-3y-9=0

-3y=9

y=9/-3

y=-3

x=0 and y = -3

check

-5x-3y-9=0

-5(0)-3(-3)-9=0

0+9-9=0

9-9=0

0=0
