(3)について質問です。sを求めるところまでは分かったのですがその後どうやってx,yを求めるのか分かりません💦どなたか教えてほしいです🙇🏻‍♀️

t=2のとき, ①は これを解くと すなわち s=1 s2-2s+1=0 (x, y) = (1,1) t=1のとき, ① は これを解くと s=0, -1 s2+s=0 すなわち (x, y)=(0, -1), (-1, 0) 以上から, 2x+3xy +2yは (x, y) = (1,1) で最大値 7, (x,y)=(0, -1, -1, 0)で最小値 -2 をとる。

It's just 35°C. When drivers stop for gas, they fill up their cars in gallons, not liters. Families shopping at the supermarket may also buy a gallon of milk.
