3x+2y=\frac{405}{30}
Ikki tarafini 30 ga bo‘ling.
3x+2y=\frac{27}{2}
\frac{405}{30} ulushini 15 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.
3x=\frac{27}{2}-2y
Ikkala tarafdan 2y ni ayirish.
\frac{3x}{3}=\frac{\frac{27}{2}-2y}{3}
Ikki tarafini 3 ga bo‘ling.
x=\frac{\frac{27}{2}-2y}{3}
3 ga bo'lish 3 ga ko'paytirishni bekor qiladi.
x=-\frac{2y}{3}+\frac{9}{2}
\frac{27}{2}-2y ni 3 ga bo'lish.
