2x+3y-17

3x+y=31

2(x-3y)=24

y=3x-2

2(x+4)=24

x+y=17

**bobpursley**, Wednesday, April 20, 2011 at 4:00pmI 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

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.
