35=-frac{3sqrt{7}}{2}*sqrt{7}+b eching

$$35 = - \frac { 3 \sqrt { 7 } } { 2 } \times \sqrt { 7 } + b$$

b uchun yechish

$$b = \frac{91}{2} = 45\frac{1}{2} = 45,5$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

Tenglamaning ikkala tarafini 2 ga ko'paytirish.

$$70=2\left(-\frac{3\sqrt{7}}{2}\right)\sqrt{7}+2b$$

2\left(-\frac{3\sqrt{7}}{2}\right) ni yagona kasrga aylantiring.

$$70=\frac{-2\times 3\sqrt{7}}{2}\sqrt{7}+2b$$

2 va 2 ni qisqartiring.

$$70=-3\sqrt{7}\sqrt{7}+2b$$

7 hosil qilish uchun \sqrt{7} va \sqrt{7} ni ko'paytirish.

$$70=-3\times 7+2b$$

-21 hosil qilish uchun -3 va 7 ni ko'paytirish.

$$70=-21+2b$$

Tomonlarni almashtirib, barcha oʻzgaruvchi shartlar chap tomonga oʻtkazing.

$$-21+2b=70$$

21 ni ikki tarafga qo’shing.

$$2b=70+21$$

91 olish uchun 70 va 21'ni qo'shing.

$$2b=91$$

Ikki tarafini 2 ga bo‘ling.

$$b=\frac{91}{2}$$
