3/4x+3/2=3/8 eching

$$\frac { 3 } { 4 } x + \frac { 3 } { 2 } = \frac { 3 } { 8 }$$

x uchun yechish

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

Chiziqli tenglamalarni yechish bo'yicha qadamlar

Ikkala tarafdan \frac{3}{2} ni ayirish.

$$\frac{3}{4}x=\frac{3}{8}-\frac{3}{2}$$

8 va 2 ning eng kichik umumiy karralisi 8 ga teng. \frac{3}{8} va \frac{3}{2} ni 8 maxraj bilan kasrlarga aylantirib oling.

$$\frac{3}{4}x=\frac{3}{8}-\frac{12}{8}$$

\frac{3}{8} va \frac{12}{8} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{3}{4}x=\frac{3-12}{8}$$

-9 olish uchun 3 dan 12 ni ayirish.

$$\frac{3}{4}x=-\frac{9}{8}$$

Ikki tarafini \frac{4}{3} va teskari kasri \frac{3}{4} ga ko‘paytiring.

$$x=-\frac{9}{8}\times \frac{4}{3}$$

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali -\frac{9}{8} ni \frac{4}{3} ga ko‘paytiring.

$$x=\frac{-9\times 4}{8\times 3}$$

\frac{-9\times 4}{8\times 3} kasridagi ko‘paytirishlarni bajaring.

$$x=\frac{-36}{24}$$

\frac{-36}{24} ulushini 12 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

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