5x+5=0

5x+5-5=0-5

5x=-5

5x/5=-5/5

x=-1

3(-1)-y=0

-3-y=0

-3+3-y=0+3

-y=3

y=-3

3x - y = 0

5x + 5 = 0

Solve for x:

5x + 5 = 0

5x = -5 [Subtract 5 from both sides]

Plug x = -1 into the first equation and solve for y:

3x - y = 0

3(-1) - y = 0 [Plugged in -1 in place of x, since x = -1]

-3 - y = 0 [Add y to both sides]
