and the equations =

1) y+2x=9

2) 2y -x =8 i tried the first part to find y and keep coming up with 0.42.... and then breaking down ...please help me ..this was one of the things i thought i COULD do

..i know i've just writen a stats problem up but i was doing this just to keep working .

my working out is like this

1) y+2x=9

2)2y-x=8 <----x2 =3) 4y-2x=16

3)-1)

= 3y = 7 or -3y=-7 and then that comes up with 0.42... or - 0.42.....
