-16+20y-64=48
2 daraja ko‘rsatkichini 4 ga hisoblang va 16 ni qiymatni oling.
-80+20y=48
-80 olish uchun -16 dan 64 ni ayirish.
20y=48+80
80 ni ikki tarafga qo’shing.
20y=128
128 olish uchun 48 va 80'ni qo'shing.
y=\frac{128}{20}
Ikki tarafini 20 ga bo‘ling.
y=\frac{32}{5}
\frac{128}{20} ulushini 4 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.
