What are the equations?

3x-10y=2 *9 > -27x+90y=-18 -x-9y=11 *10>=10x-90y=110

OpenStudy (anonymous):

What are they asking you to do? Solve for x and y? Find the slope? Solve the equation? Or what?

OpenStudy (anonymous):

I am eliminating y

OpenStudy (anonymous):

so far I think its 37x=92 but I dont think that is right

OpenStudy (anonymous):

6x-y+3z=5 x+3y-z=-1 3x+3y-4z

OpenStudy (anonymous):

Solving this system.
