Tomonlarni almashtirib, barcha oʻzgaruvchi shartlar chap tomonga oʻtkazing.

$$-20385D_{0}=29Y_{3}-20Y-2XY$$

Ikki tarafini -20385 ga bo‘ling.

$$\frac{-20385D_{0}}{-20385}=\frac{29Y_{3}-20Y-2XY}{-20385}$$

-20385 ga bo'lish -20385 ga ko'paytirishni bekor qiladi.

$$D_{0}=\frac{29Y_{3}-20Y-2XY}{-20385}$$

29Y_{3}-20Y-2XY ni -20385 ga bo'lish.

$$D_{0}=\frac{2XY}{20385}+\frac{4Y}{4077}-\frac{29Y_{3}}{20385}$$

X uchun yechish
