Hi everyone! Thanks for all of your help on the last question. I ended up with an A on my last test. Talking to you really helped and when I saw the questions on the test I knew what to do.

I am stuck again. The question says to use three methods to solve for the following system of equations.

x-y=-5

x+3y=3

I need to solve by graphing, the addition method and the substitution method.

I think I have solved by graphing, please let me know if I have done this part correctly

the points I came up with are (0,-5) (-5,0) and for the second one (0,1) (1,0)

the addition method is where I beging to really struggle... this is what I have written

x-y=-5

x+3y=3

_______

2x+2y=-2

as for the substitution method... which was easy in class.... I now.. dont have a clue

thanks in advance
