Best ResponseYou've already chosen the best response.05X+3Y=11 3Y=115X (subtracted 5X on both sides) Y=11/35X/3 (divided both sides by 3) the equation is 7X2Y=17 (but we know what Y is in terms of X so we plug in 11/35X/3 for Y) 7X2(11/35X/3)=17 7X+22/3+10X/3=17 7X+10X/3=1722/3 21X/3+10X/3=51/322/3 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=11/35X/3 we will put 29/31 so we have Y=11/35(29/(31*3))
