x\times 18=4\left(11-x\right)
x qiymati 0 teng bo‘lmaydi, chunki nolga bo‘lish mumkin emas. Tenglamaning ikkala tarafini 4x ga, 4,x ning eng kichik karralisiga ko‘paytiring.
x\times 18=44-4x
4 ga 11-x ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
x\times 18+4x=44
4x ni ikki tarafga qo’shing.
22x=44
22x ni olish uchun x\times 18 va 4x ni birlashtirish.
x=\frac{44}{22}
Ikki tarafini 22 ga bo‘ling.
x=2
2 ni olish uchun 44 ni 22 ga bo‘ling.
