Yechim qadamlari

R_{2}^{2} hosil qilish uchun R_{2} va R_{2} ni ko'paytirish.

$$4R_{1}+7R_{2}\times 5R_{1}-3R_{2}^{2}\times 2-R_{1}$$

35 hosil qilish uchun 7 va 5 ni ko'paytirish.

$$4R_{1}+35R_{2}R_{1}-3R_{2}^{2}\times 2-R_{1}$$

6 hosil qilish uchun 3 va 2 ni ko'paytirish.

$$4R_{1}+35R_{2}R_{1}-6R_{2}^{2}-R_{1}$$

3R_{1} ni olish uchun 4R_{1} va -R_{1} ni birlashtirish.

$$3R_{1}+35R_{2}R_{1}-6R_{2}^{2}$$

R_1 ga nisbatan hosilani topish

$$35R_{2}+3$$
