so you set 20 + 9t > 0

where t > -(20/9)

and then -15 - 7t > 0

where t < -(15/7)

and so you get

-(15/7) > t > -(20/9)

then (normally) from there we would take all the values of t in that restriction

(say for instance you had .5>t>2.5 - so t=1&2, and then you would plug those t values back into your x=blah and y=blah - and those are your solutions)

but with this problem - there are no integers in that restriction so that makes me wanna say no solutions ... ?
