so, so far, you have 2 equations , 2 variables, the system is solvable. Do it, show me your brain, please

loser66 · Answer

And what do you want me to do for part 2? check your work?

anonymous · Answer

the first would be y=7+1/2x right?

loser66 · Answer

why y? why not x? x is quite easier, right?

anonymous · Answer

then that is x=-2y+14

loser66 · Answer

ok, plug to second one to get y.  
the net is so slow, sorry for that.

anonymous · Answer
