20x=300-50y
Ikkala tarafdan 50y ni ayirish.
\frac{20x}{20}=\frac{300-50y}{20}
Ikki tarafini 20 ga bo‘ling.
x=\frac{300-50y}{20}
20 ga bo'lish 20 ga ko'paytirishni bekor qiladi.
x=-\frac{5y}{2}+15
300-50y ni 20 ga bo'lish.
50y=300-20x
Ikkala tarafdan 20x ni ayirish.
\frac{50y}{50}=\frac{300-20x}{50}
Ikki tarafini 50 ga bo‘ling.
y=\frac{300-20x}{50}
50 ga bo'lish 50 ga ko'paytirishni bekor qiladi.
y=-\frac{2x}{5}+6
