system of equations thank you
2x+3y17
3x+y=31
2(x3y)=24
y=3x2
2(x+4)=24
x+y=17

I will do the second:
2x6y=24
3x+y=2
multipy the second equation by 6 to eliminate the y's.
2x6y=24
18x+6y=12
add the equations
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
