Im not good at algebra, you tell me to find x and I have no idea how. So I don't try anymore. Sorry. But thank you ^^

uri · Answer

You want to know how did i find x?

anonymous · Answer

no, its not going to stick in my mind so I have no use to try. Im an artist, I have no use for algebra. ^^

Well add both the eq  so x+x=2x and +2y-2y will be cancelled and 11-1 =10.

uri · Answer

Now you have to find y.

anonymous · Answer

see....I have no idea what your talking about. im god awful at anything to do with math..

uri · Answer

x - 2y = -1
5-2y=-1(put the value of x in eq no.2)
-2y=-1-5
-2y=-6
y=-6/-2
y=3
