Please type that fraction as (5/6), so that there's no ambiguity (did you mean (5/6)x, or did you mean (5x/6)? )
There are several approaches you could take here. One would be to substitute (5/6)x+1 for y in the second equation. This eliminates y. Mult. the resulting equation by 6 to eliminate the fraction (5/6). solve the resulting equation for x.
