70-2q-2q=80
-2q ni olish uchun -q va -q ni birlashtirish.
70-4q=80
-4q ni olish uchun -2q va -2q ni birlashtirish.
-4q=80-70
Ikkala tarafdan 70 ni ayirish.
-4q=10
10 olish uchun 80 dan 70 ni ayirish.
q=\frac{10}{-4}
Ikki tarafini -4 ga bo‘ling.
q=-\frac{5}{2}
\frac{10}{-4} ulushini 2 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.
