Răspuns :
Nr elevilor + inca unul impartit la 2 da numarul de microscoape, adica (x+1):2=m => x=2m-1
Numarul de elevi impartit la 3 da numarul de microscoape minus 4 neocupate , adica x:3=m-4 => (2m-1):3=m-4 2m-1=(m-4)*3 2m - 1 = 3m -12 12-1=3m-2m
m=11
x=2m-1 => x=21
11 microscoape si 21 elevi

x=nr microscoape
2{x-1)+1=3(x-4)
2x-2+1=3x-12
2x-1=3x-12
12-1=3x-2x
x=11 microscoape
2(x-1)+1=2(11-1)+1=20+1=21elevi
2{x-1)+1=3(x-4)
2x-2+1=3x-12
2x-1=3x-12
12-1=3x-2x
x=11 microscoape
2(x-1)+1=2(11-1)+1=20+1=21elevi
