5-x/30=1/20 eching

$$\frac{ 5-x }{ 30 } = \frac{ 1 }{ 20 }$$

x uchun yechish

$$x = \frac{7}{2} = 3\frac{1}{2} = 3,5$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

Ikkala tarafini 30 ga ko‘paytiring.

$$5-x=\frac{1}{20}\times 30$$

\frac{30}{20} hosil qilish uchun \frac{1}{20} va 30 ni ko'paytirish.

$$5-x=\frac{30}{20}$$

\frac{30}{20} ulushini 10 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$5-x=\frac{3}{2}$$

Ikkala tarafdan 5 ni ayirish.

$$-x=\frac{3}{2}-5$$

5 ni \frac{10}{2} kasrga o‘giring.

$$-x=\frac{3}{2}-\frac{10}{2}$$

\frac{3}{2} va \frac{10}{2} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$-x=\frac{3-10}{2}$$

-7 olish uchun 3 dan 10 ni ayirish.

$$-x=-\frac{7}{2}$$

Ikkala tarafini -1 ga ko‘paytiring.

$$x=\frac{7}{2}$$
