78=1/2x(64+13) eching

$$78= \frac{ 1 }{ 2 } x(64+13)$$

x uchun yechish

$$x = \frac{156}{77} = 2\frac{2}{77} \approx 2,025974026$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

77 olish uchun 64 va 13'ni qo'shing.

$$78=\frac{1}{2}x\times 77$$

\frac{77}{2} hosil qilish uchun \frac{1}{2} va 77 ni ko'paytirish.

$$78=\frac{77}{2}x$$

Tomonlarni almashtirib, barcha oʻzgaruvchi shartlar chap tomonga oʻtkazing.

$$\frac{77}{2}x=78$$

Ikki tarafini \frac{2}{77} va teskari kasri \frac{77}{2} ga ko‘paytiring.

$$x=78\times \frac{2}{77}$$

78\times \frac{2}{77} ni yagona kasrga aylantiring.

$$x=\frac{78\times 2}{77}$$

156 hosil qilish uchun 78 va 2 ni ko'paytirish.

$$x=\frac{156}{77}$$
