r uchun yechish
r=\frac{2\left(-3s+t-2\right)}{3}
s uchun yechish
s=\frac{t}{3}-\frac{r}{2}-\frac{2}{3}

3r+6s=2t-4
3 ga r+2s ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
3r=2t-4-6s
Ikkala tarafdan 6s ni ayirish.
3r=-6s+2t-4
Tenglama standart shaklda.
\frac{3r}{3}=\frac{-6s+2t-4}{3}
Ikki tarafini 3 ga bo‘ling.
r=\frac{-6s+2t-4}{3}
3 ga bo'lish 3 ga ko'paytirishni bekor qiladi.
r=\frac{2t}{3}-2s-\frac{4}{3}
-4+2t-6s ni 3 ga bo'lish.
3r+6s=2t-4
3 ga r+2s ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
6s=2t-4-3r
Ikkala tarafdan 3r ni ayirish.
6s=-3r+2t-4
Tenglama standart shaklda.
\frac{6s}{6}=\frac{-3r+2t-4}{6}
Ikki tarafini 6 ga bo‘ling.
s=\frac{-3r+2t-4}{6}
6 ga bo'lish 6 ga ko'paytirishni bekor qiladi.
s=\frac{t}{3}-\frac{r}{2}-\frac{2}{3}
2t-4-3r ni 6 ga bo'lish.
