-9/7-1/2w=-9/5 eching

$$- \frac { 9 } { 7 } - \frac { 1 } { 2 } w = - \frac { 9 } { 5 }$$

w uchun yechish

$$w = \frac{36}{35} = 1\frac{1}{35} \approx 1,028571429$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

\frac{9}{7} ni ikki tarafga qo’shing.

$$-\frac{1}{2}w=-\frac{9}{5}+\frac{9}{7}$$

5 va 7 ning eng kichik umumiy karralisi 35 ga teng. -\frac{9}{5} va \frac{9}{7} ni 35 maxraj bilan kasrlarga aylantirib oling.

$$-\frac{1}{2}w=-\frac{63}{35}+\frac{45}{35}$$

-\frac{63}{35} va \frac{45}{35} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$-\frac{1}{2}w=\frac{-63+45}{35}$$

-18 olish uchun -63 va 45'ni qo'shing.

$$-\frac{1}{2}w=-\frac{18}{35}$$

Ikki tarafini -2 va teskari kasri -\frac{1}{2} ga ko‘paytiring.

$$w=-\frac{18}{35}\left(-2\right)$$

-\frac{18}{35}\left(-2\right) ni yagona kasrga aylantiring.

$$w=\frac{-18\left(-2\right)}{35}$$

36 hosil qilish uchun -18 va -2 ni ko'paytirish.

$$w=\frac{36}{35}$$
