Question 1065941
EDIT:  MISTAKE HAS BEEN ADJUSTED.
RESULT NOW CORRECT


This is for #1 only.


x and y integers
{{{system(xy=14,y=-3+5x)}}}


{{{x(5x-3)=14}}}
{{{5x^2-3x-14=0}}}
and since you expect x and y to be integers, you should try factorization.


{{{(5x+7)(x-2)=0}}}

You want the INTEGER, so this will be {{{highlight(x=2)}}} meaning that {{{highlight(y=7)}}}.
