5\times 4+5x\left(-6\right)=-11x
x qiymati 0 teng bo‘lmaydi, chunki nolga bo‘lish mumkin emas. Tenglamaning ikkala tarafini 5x ga, x,5 ning eng kichik karralisiga ko‘paytiring.
20+5x\left(-6\right)=-11x
20 hosil qilish uchun 5 va 4 ni ko'paytirish.
20-30x=-11x
-30 hosil qilish uchun 5 va -6 ni ko'paytirish.
20-30x+11x=0
11x ni ikki tarafga qo’shing.
20-19x=0
-19x ni olish uchun -30x va 11x ni birlashtirish.
-19x=-20
Ikkala tarafdan 20 ni ayirish. Har qanday sonni noldan ayirsangiz, o‘zining manfiyi chiqadi.
x=\frac{-20}{-19}
Ikki tarafini -19 ga bo‘ling.
x=\frac{20}{19}
Ikkala surat va maxrajdan manfiy belgini olib tashlash bilan \frac{-20}{-19} kasrini \frac{20}{19} ga soddalashtirish mumkin.
