system of equations thank you
2x+3y-17
3x+y=31

2(x-3y)=24
y=3x-2

2(x+4)=24
x+y=17

I will do the second:

2x-6y=24
-3x+y=-2

multipy the second equation by 6 to eliminate the y's.
2x-6y=24
-18x+6y=-12

-16x=12
x=-3/4
then solve for y by putting that x back into one of the equations.

I will be happy to check your work on the others.

i don't think that's write cuz they show me another way
