250*42*20=m*21*20+(m-50)*336 eching

$$250 \times 42 \times 20 = m \times 21 \times 20 + ( m - 50 ) \times 336$$

m uchun yechish

$$m=300$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

10500 hosil qilish uchun 250 va 42 ni ko'paytirish.

$$10500\times 20=m\times 21\times 20+\left(m-50\right)\times 336$$

210000 hosil qilish uchun 10500 va 20 ni ko'paytirish.

$$210000=m\times 21\times 20+\left(m-50\right)\times 336$$

420 hosil qilish uchun 21 va 20 ni ko'paytirish.

$$210000=m\times 420+\left(m-50\right)\times 336$$

m-50 ga 336 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

$$210000=m\times 420+336m-16800$$

756m ni olish uchun m\times 420 va 336m ni birlashtirish.

$$210000=756m-16800$$

Tomonlarni almashtirib, barcha oʻzgaruvchi shartlar chap tomonga oʻtkazing.

$$756m-16800=210000$$

16800 ni ikki tarafga qo’shing.

$$756m=210000+16800$$

226800 olish uchun 210000 va 16800'ni qo'shing.

$$756m=226800$$

Ikki tarafini 756 ga bo‘ling.

$$m=\frac{226800}{756}$$

300 ni olish uchun 226800 ni 756 ga bo‘ling.

$$m=300$$
