3-(-4)/-2-a=-10-(-3)/-5-6 eching

$$\frac { 3 - ( - 4 ) } { - 2 - a } = \frac { - 10 - ( - 3 ) } { - 5 - 6 }$$

a uchun yechish

$$a=-13$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

a qiymati -2 teng bo‘lmaydi, chunki nolga bo‘lish mumkin emas. Tenglamaning ikkala tarafini -a-2 ga ko'paytirish.

$$3-\left(-4\right)=\left(\frac{1}{11}a+\frac{2}{11}\right)\left(-10-\left(-3\right)\right)$$

-4 ning teskarisi 4 ga teng.

$$3+4=\left(\frac{1}{11}a+\frac{2}{11}\right)\left(-10-\left(-3\right)\right)$$

7 olish uchun 3 va 4'ni qo'shing.

$$7=\left(\frac{1}{11}a+\frac{2}{11}\right)\left(-10-\left(-3\right)\right)$$

-3 ning teskarisi 3 ga teng.

$$7=\left(\frac{1}{11}a+\frac{2}{11}\right)\left(-10+3\right)$$

-7 olish uchun -10 va 3'ni qo'shing.

$$7=\left(\frac{1}{11}a+\frac{2}{11}\right)\left(-7\right)$$

\frac{1}{11}a+\frac{2}{11} ga -7 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

$$7=-\frac{7}{11}a-\frac{14}{11}$$

Tomonlarni almashtirib, barcha oʻzgaruvchi shartlar chap tomonga oʻtkazing.

$$-\frac{7}{11}a-\frac{14}{11}=7$$

\frac{14}{11} ni ikki tarafga qo’shing.

$$-\frac{7}{11}a=7+\frac{14}{11}$$

\frac{91}{11} olish uchun 7 va \frac{14}{11}'ni qo'shing.

$$-\frac{7}{11}a=\frac{91}{11}$$

Ikki tarafini -\frac{11}{7} va teskari kasri -\frac{7}{11} ga ko‘paytiring.

$$a=\frac{91}{11}\left(-\frac{11}{7}\right)$$

-13 hosil qilish uchun \frac{91}{11} va -\frac{11}{7} ni ko'paytirish.

$$a=-13$$
