Question

la o pescarie sunt 230 kg de caras,210 kg,crap si cateva kg de somn .daca la cantitatea de somn adaugam cantitatea de crap,ar fi cu 30 kg mai mult decat cantitatea de caras .cate kg de peste erau in total?
 

Answer 1

x=caras
y=crap
z=somn

x=230 ( caras )
y=210 ( crap )

z+210=230+30
z+210=260
z=260-210
z=50 kg ( somn )

x+y+z=?
230+210+50=490 kg de peste in total

Answer 2

x-cantitatea de somn

(x+210)-30=230

x+210= 230+30

x+210=260

x=260-210

x=50kg de somn
