y=3x+5
y=3x-5
(I remember that paralell lines have same slope and paralell lines with different y intercepts have no solutions so I wuld say no solutions)
I will solve
set them eaqual to each other
3x+5=y=3x-5
3x+5=3x-5
subtract 5 from both sides
3x=3x-10
subtract 3x from both sides
0=-10
false
there is no solution
