Kama natoka kapa Jibu ni 27kg.
Hizi hesabu nilizipiga darasa la tano.
Tunasema let Paka =X Panya=Y na Mbwa =Z
1.Paka + Panya=10kg
2.Mbwa + Panya=20kg
3.Mbwa + Paka = 24kg

Sasa Paka + Panya + Mbwa = 27 simple

Leta vitu vyenye afya sio vitu hata mtoto wa premary atafanya.:juggle:

Let
X= Sungura
Y= Paka
Z= Mbwa

X+Y=10 ......(1)
X+Z=20 ......(2)
Y+Z=24 ......(3)

From eqn(1)
X=10-Y ......(4)

Substitue eqn(4) into eqn(2)
(10-Y)+Z=20
Z-Y=10 ......(5)

Solve eqn(3) and eqn(5) simultaneously
Z+Y=24 ......(3)
Z-Y=10 ......(5)
2Z=34
Z=17

Then;
Y=7
X=3

X+Y+Z=3+7+17=27 Ans
