Aynu ka soo qaadno in labada lambar ay yihiin x iyo y. Marka loo eego dhibaatadu, waxaynu ognahay in:
x + y = 44 ( isla’egta 1 ) x – y = 14 ( isla’egta 2 )
Si loo xalliyo x iyo y, waxaan isticmaali karnaa habka tirtirka, taas oo ku lug leh ku darista ama kala-goynta labada isla’egta si loo tirtiro mid ka mid ah doorsoomayaasha. Xaaladdan oo kale, waxaan ku dari karnaa isla’egta 1 iyo isla’egta 2 si loo baabi’iyo y:
(x + y) + (x – y) = 44 + 14
Fududeynta isla’egtan, waxaan helnaa:
2x = 58
U qeybinta labada dhinac 2, waxaan heleynaa:
x = 29
Hadda oo aan ognahay x = 29, waxaan isticmaali karnaa isla’egta 1 si aan u xalino y:
x + y = 44
29 + y = 44
Marka laga soo tago 29 labada dhinac, waxaan heleynaa:
y = 15
Haddaba, labada lambar waa 29 iyo 15, maadaama wadartoodu tahay 44, farqigooduna yahay 14.
