n(56-14)/2=231 eching

$$\frac { n ( 56 - 14 ) } { 2 } = 231$$

n uchun yechish

$$n=11$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

Ikkala tarafini 2 ga ko‘paytiring.

$$n\left(56-14\right)=231\times 2$$

42 olish uchun 56 dan 14 ni ayirish.

$$n\times 42=231\times 2$$

462 hosil qilish uchun 231 va 2 ni ko'paytirish.

$$n\times 42=462$$

Ikki tarafini 42 ga bo‘ling.

$$n=\frac{462}{42}$$

11 ni olish uchun 462 ni 42 ga bo‘ling.

$$n=11$$
