3-5t-5t=78
Ikkala tarafdan 5t ni ayirish.
3-10t=78
-10t ni olish uchun -5t va -5t ni birlashtirish.
-10t=78-3
Ikkala tarafdan 3 ni ayirish.
-10t=75
75 olish uchun 78 dan 3 ni ayirish.
t=\frac{75}{-10}
Ikki tarafini -10 ga bo‘ling.
t=-\frac{15}{2}
\frac{75}{-10} ulushini 5 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.
