-3x + 4y = 1

Answer 1

any1 can post numbers zordoloom
2x+y=3 same thing as y=3-2x plug this into bottom equation and get
-3x +4(3-2x)=1 then get -3x + 12 - 8x= 1 then -11x +12=1 then -11x=-11 then divide by -11 and get that x = 1
plug this into original and get that 2+y=3 and find out that y = 1
therefor y=1 and x=1
