Question

intr o curte sunt 116 pasari gaini curci rate stiind ca gaini sunt cu 17 mai multe decit curci si rate sunt cu 9 msi multe decit curci . sa se afle cite psari de fiecare fel sunt in curte

Answer 1

R(Rate) + G ( gaini) + C( curci) = 116 gaini
17+C(curci) = Gaini
Curci+9= Rate
Rezolvare:
9+c+17+c+c=116 gaini
26+ 3 x c = 116 gaini
3 x c= 116 gaini- 26
3 x c= 90 gaini
c = 90 : 3
c = 30, R= 39, g= 47
Daca sunt greseli, Imi pare rau

Answer 2

g+c+r=116
g=c+17
r=c+9

c+17+c+c+9=116
3c=116-26
c=90:3=30  curci
g=c+17=30+17=47 gaini
r=c+9=30+9=39  rate
