Răspuns :
x-suma depusa de Andrei
y-suma depusa de Alexandru
x+y=360
x=80/100 *y
x=8/10*y
x=4y/5
4y/5 +y=360 aducem la acelasi numitor
4y+5y=1800
9y=1800
y=200
x=160
y-suma depusa de Alexandru
x+y=360
x=80/100 *y
x=8/10*y
x=4y/5
4y/5 +y=360 aducem la acelasi numitor
4y+5y=1800
9y=1800
y=200
x=160
360 din 80 = 360 x 80 supra 100= 288 . Suma depusa de Andrei este 288 .
Suma depusa de alexandru=360-288=72
288+72=360
Suma depusa de alexandru=360-288=72
288+72=360
