2(4xw)+2w=140 eching

$$2 ( 4 x w ) + 2 w = 140$$

w uchun yechish

$$w=\frac{70}{4x+1}$$

$$x\neq -\frac{1}{4}$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

8 hosil qilish uchun 2 va 4 ni ko'paytirish.

$$8xw+2w=140$$

w'ga ega bo'lgan barcha shartlarni birlashtirish.

$$\left(8x+2\right)w=140$$

Ikki tarafini 8x+2 ga bo‘ling.

$$\frac{\left(8x+2\right)w}{8x+2}=\frac{140}{8x+2}$$

8x+2 ga bo'lish 8x+2 ga ko'paytirishni bekor qiladi.

$$w=\frac{140}{8x+2}$$

140 ni 8x+2 ga bo'lish.

$$w=\frac{70}{4x+1}$$

x uchun yechish

$$x=-\frac{1}{4}+\frac{35}{2w}$$

$$w\neq 0$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

8 hosil qilish uchun 2 va 4 ni ko'paytirish.

$$8xw+2w=140$$

Ikkala tarafdan 2w ni ayirish.

$$8xw=140-2w$$

Tenglama standart shaklda.

$$8wx=140-2w$$

Ikki tarafini 8w ga bo‘ling.

$$\frac{8wx}{8w}=\frac{140-2w}{8w}$$

8w ga bo'lish 8w ga ko'paytirishni bekor qiladi.

$$x=\frac{140-2w}{8w}$$

140-2w ni 8w ga bo'lish.

$$x=-\frac{1}{4}+\frac{35}{2w}$$
