5X+3Y=-11     
3Y=-11-5X      (subtracted 5X on both sides)
Y=-11/3-5X/3  (divided both sides by 3)
the equation is
7X-2Y=17       (but we know what Y is in terms of X so we plug in -11/3-5X/3 for Y)
7X-2(-11/3-5X/3)=17
7X+22/3+10X/3=17
7X+10X/3=17-22/3
21X/3+10X/3=51/3-22/3
31X/3=29/3
X=29/3 * 3/31
X=29/31
but remember we solved that first equation for Y and it was in terms of just X 
so we can easily find what Y is by just plugging in what we found for X
Since X=29/31 wherever we see a X in Y=-11/3-5X/3  we will put 29/31
so we have Y=-11/3-5(29/(31*3))
