5*20+(x-5)*4=(5*20+44)*09 eching

$$5 \times 20 + ( x - 5 ) \times 4 = ( 5 \times 20 + 44 ) \times 09$$

x uchun yechish

$$x=-20$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

100 hosil qilish uchun 5 va 20 ni ko'paytirish.

$$100+\left(x-5\right)\times 4=\left(5\times 20+44\right)\times 0\times 9$$

x-5 ga 4 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

$$100+4x-20=\left(5\times 20+44\right)\times 0\times 9$$

80 olish uchun 100 dan 20 ni ayirish.

$$80+4x=\left(5\times 20+44\right)\times 0\times 9$$

100 hosil qilish uchun 5 va 20 ni ko'paytirish.

$$80+4x=\left(100+44\right)\times 0\times 9$$

144 olish uchun 100 va 44'ni qo'shing.

$$80+4x=144\times 0\times 9$$

0 hosil qilish uchun 144 va 0 ni ko'paytirish.

$$80+4x=0\times 9$$

0 hosil qilish uchun 0 va 9 ni ko'paytirish.

$$80+4x=0$$

Ikkala tarafdan 80 ni ayirish. Har qanday sonni noldan ayirsangiz, o‘zining manfiyi chiqadi.

$$4x=-80$$

Ikki tarafini 4 ga bo‘ling.

$$x=\frac{-80}{4}$$

-20 ni olish uchun -80 ni 4 ga bo‘ling.

$$x=-20$$
