any idea?

anonymous · Answer

I don't want an answer, just a little help. I'm not sure how i solve for y :/

anonymous · Answer

u have to emit the x from the equation

anonymous · Answer

so u will multiply the first equatin in -7 and the second one in 13

anonymous · Answer

Can you show me how that would look?

anonymous · Answer

-7*(first equation)
13*(second equation)

anonymous · Answer

(-7*13x)-7*-6y=20*-7____>-91x+42y=-140
tell me the second one
