Question

Ex: 23 plsss repede!!!!!

Answer 1

Notam :

gaini =g

rate =r

gaste =x

g+r+x=77

g+r=49

r+x=48

g,r,x=?

g+r=49 => g= 49-r

r+x=48=> x=48-r

inlocuim in prima :

g+r+x=77

49-r+r+48-r=77

-r =77 -49-48

-r=-20

r=20 (sunt 20 de rate)

g=49-r

g=29 (sunt 29 de gaini)

x=48-r

x=28 (sunt 28 de gaste)
