SOLVE for x=.2y
0.25 + x = y
y = -.0625 ~ -1/16
IMO E

I get a different result, why??

0.25+x=y thus

y/x= 0.25+x/x=0.2

0.25/x +x/x = 0.25/x +1 = 0.2

0.25=-0.8x
x=0.25/(-0.8)=-5/16

Any clues where I went wrong?

We see that y = 0.2x, thus:

0.25 + x = 0.2x

0.25 = -0.8x

25 = -80x

x = 25/-80 = -5/16

So y = 0.2(-5/16) = -1/16.

Question is asking y and you have found out x.

Thanks
