\frac{8}{5}+3y-6y=-\frac{1}{5}
Ikkala tarafdan 6y ni ayirish.
\frac{8}{5}-3y=-\frac{1}{5}
-3y ni olish uchun 3y va -6y ni birlashtirish.
-3y=-\frac{1}{5}-\frac{8}{5}
Ikkala tarafdan \frac{8}{5} ni ayirish.
-3y=\frac{-1-8}{5}
-\frac{1}{5} va \frac{8}{5} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.
-3y=-\frac{9}{5}
-9 olish uchun -1 dan 8 ni ayirish.
y=\frac{-\frac{9}{5}}{-3}
Ikki tarafini -3 ga bo‘ling.
y=\frac{-9}{5\left(-3\right)}
\frac{-\frac{9}{5}}{-3} ni yagona kasrga aylantiring.
y=\frac{-9}{-15}
