(20*4+30*2)(1+16%)=5*20+30x eching

$$( 20 \times 4 + 30 \times 2 ) ( 1 + 16 \% ) = 5 \times 20 + 30 x$$

x uchun yechish

$$x = \frac{52}{25} = 2\frac{2}{25} = 2,08$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

80 hosil qilish uchun 20 va 4 ni ko'paytirish. 60 hosil qilish uchun 30 va 2 ni ko'paytirish.

$$\left(80+60\right)\left(1+\frac{16}{100}\right)=5\times 20+30x$$

140 olish uchun 80 va 60'ni qo'shing.

$$140\left(1+\frac{16}{100}\right)=5\times 20+30x$$

\frac{16}{100} ulushini 4 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$140\left(1+\frac{4}{25}\right)=5\times 20+30x$$

1 ni \frac{25}{25} kasrga o‘giring.

$$140\left(\frac{25}{25}+\frac{4}{25}\right)=5\times 20+30x$$

\frac{25}{25} va \frac{4}{25} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$140\times \frac{25+4}{25}=5\times 20+30x$$

29 olish uchun 25 va 4'ni qo'shing.

$$140\times \frac{29}{25}=5\times 20+30x$$

140\times \frac{29}{25} ni yagona kasrga aylantiring.

$$\frac{140\times 29}{25}=5\times 20+30x$$

4060 hosil qilish uchun 140 va 29 ni ko'paytirish.

$$\frac{4060}{25}=5\times 20+30x$$

\frac{4060}{25} ulushini 5 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{812}{5}=5\times 20+30x$$

100 hosil qilish uchun 5 va 20 ni ko'paytirish.

$$\frac{812}{5}=100+30x$$

Tomonlarni almashtirib, barcha oʻzgaruvchi shartlar chap tomonga oʻtkazing.

$$100+30x=\frac{812}{5}$$

Ikkala tarafdan 100 ni ayirish.

$$30x=\frac{812}{5}-100$$

100 ni \frac{500}{5} kasrga o‘giring.

$$30x=\frac{812}{5}-\frac{500}{5}$$

\frac{812}{5} va \frac{500}{5} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$30x=\frac{812-500}{5}$$

312 olish uchun 812 dan 500 ni ayirish.

$$30x=\frac{312}{5}$$

Ikki tarafini 30 ga bo‘ling.

$$x=\frac{\frac{312}{5}}{30}$$

\frac{\frac{312}{5}}{30} ni yagona kasrga aylantiring.

$$x=\frac{312}{5\times 30}$$

150 hosil qilish uchun 5 va 30 ni ko'paytirish.

$$x=\frac{312}{150}$$

\frac{312}{150} ulushini 6 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$x=\frac{52}{25}$$
