3=4/5(h+2) eching

$$3 = \frac { 4 } { 5 } ( h + 2 )$$

h uchun yechish

$$h = \frac{7}{4} = 1\frac{3}{4} = 1,75$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

Ikki tarafini \frac{5}{4} va teskari kasri \frac{4}{5} ga ko‘paytiring.

$$3\times \frac{5}{4}=h+2$$

3\times \frac{5}{4} ni yagona kasrga aylantiring.

$$\frac{3\times 5}{4}=h+2$$

15 hosil qilish uchun 3 va 5 ni ko'paytirish.

$$\frac{15}{4}=h+2$$

Tomonlarni almashtirib, barcha oʻzgaruvchi shartlar chap tomonga oʻtkazing.

$$h+2=\frac{15}{4}$$

Ikkala tarafdan 2 ni ayirish.

$$h=\frac{15}{4}-2$$

2 ni \frac{8}{4} kasrga o‘giring.

$$h=\frac{15}{4}-\frac{8}{4}$$

\frac{15}{4} va \frac{8}{4} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$h=\frac{15-8}{4}$$

7 olish uchun 15 dan 8 ni ayirish.

$$h=\frac{7}{4}$$
