-7/2v-5=7/3v+5/2 eching

$$- \frac { 7 } { 2 } v - 5 = \frac { 7 } { 3 } v + \frac { 5 } { 2 }$$

v uchun yechish

$$v = -\frac{9}{7} = -1\frac{2}{7} \approx -1,285714286$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

Ikkala tarafdan \frac{7}{3}v ni ayirish.

$$-\frac{7}{2}v-5-\frac{7}{3}v=\frac{5}{2}$$

-\frac{35}{6}v ni olish uchun -\frac{7}{2}v va -\frac{7}{3}v ni birlashtirish.

$$-\frac{35}{6}v-5=\frac{5}{2}$$

5 ni ikki tarafga qo’shing.

$$-\frac{35}{6}v=\frac{5}{2}+5$$

5 ni \frac{10}{2} kasrga o‘giring.

$$-\frac{35}{6}v=\frac{5}{2}+\frac{10}{2}$$

\frac{5}{2} va \frac{10}{2} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$-\frac{35}{6}v=\frac{5+10}{2}$$

15 olish uchun 5 va 10'ni qo'shing.

$$-\frac{35}{6}v=\frac{15}{2}$$

Ikki tarafini -\frac{6}{35} va teskari kasri -\frac{35}{6} ga ko‘paytiring.

$$v=\frac{15}{2}\left(-\frac{6}{35}\right)$$

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali \frac{15}{2} ni -\frac{6}{35} ga ko‘paytiring.

$$v=\frac{15\left(-6\right)}{2\times 35}$$

\frac{15\left(-6\right)}{2\times 35} kasridagi ko‘paytirishlarni bajaring.

$$v=\frac{-90}{70}$$

\frac{-90}{70} ulushini 10 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$v=-\frac{9}{7}$$
