Question

Pe santierul Ya-ba-da-ba-doo, Fred si Barney au o gramada de bolovanipe care ii aseaza in ladite.Daca in fiecare ladita ar pune 4 bolovani, ar mai trebui 3 ladite.Daca in fiecare ladita ar pune 5 bolovani, ar ramane goale 2 ladite.Cati bolovani si cate ladite sunt?

Answer 1

fie x nr de bolovani, iar y nr de ladite
x=4(y+3) => x=4y+12
x=5(y-2) => x=5y-10

4y+12=5y-10 => 10+12=5y-4y => y=22, iar x=4y+12=4*22+12=88+12=100
