225-72y=1
2 daraja ko‘rsatkichini 15 ga hisoblang va 225 ni qiymatni oling.
-72y=1-225
Ikkala tarafdan 225 ni ayirish.
-72y=-224
-224 olish uchun 1 dan 225 ni ayirish.
y=\frac{-224}{-72}
Ikki tarafini -72 ga bo‘ling.
y=\frac{28}{9}
\frac{-224}{-72} ulushini -8 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.
