12x=300-15y
Ikkala tarafdan 15y ni ayirish.
\frac{12x}{12}=\frac{300-15y}{12}
Ikki tarafini 12 ga bo‘ling.
x=\frac{300-15y}{12}
12 ga bo'lish 12 ga ko'paytirishni bekor qiladi.
x=-\frac{5y}{4}+25
300-15y ni 12 ga bo'lish.
15y=300-12x
Ikkala tarafdan 12x ni ayirish.
\frac{15y}{15}=\frac{300-12x}{15}
Ikki tarafini 15 ga bo‘ling.
y=\frac{300-12x}{15}
15 ga bo'lish 15 ga ko'paytirishni bekor qiladi.
y=-\frac{4x}{5}+20
