Ok. Got what should be a simple problem here but it has me confused and annoyed.

Supposed to be solving by elimination method.

$\displaystyle

5x{+}2y{=}11

$

$\displaystyle

7x{+}8y{=}7

$

I worked on solving this with what I know so far and I come up with pretty ugly fractions. Im thinking that there is something that I am missing and could use a little help here.
