For my hw i have to graph the following equations

Question

1) x - 3y -5 = 0 and 2x = 1 - 3y

2) y - 3x =5 and 3x = 7 + y

3) x = 3y and x +2 = 11

4) y = 2/5x + 1 and x + 2y +11

After done graphing the equations i have to state if there are zero, one, or many solutions.

I have already done the problems and graphed them and here are my answers

1) 1 solution

2) none

3) 1 solution

4) 1 solution

Answer 1

1,2,3 are correct. It looks like you skipped an equal sign in the second equation in 4.

Answer 2

correct.
