4\times 3+20x\left(-\frac{1}{4}\right)-10\times 3=20x\times \frac{3}{5}-5\times 9
x qiymati 0 teng bo‘lmaydi, chunki nolga bo‘lish mumkin emas. Tenglamaning ikkala tarafini 20x ga, 5x,4,2x,5,4x ning eng kichik karralisiga ko‘paytiring.
12+20x\left(-\frac{1}{4}\right)-30=20x\times \frac{3}{5}-5\times 9
Ko‘paytirishlarni bajaring.
12-5x-30=20x\times \frac{3}{5}-5\times 9
-5 hosil qilish uchun 20 va -\frac{1}{4} ni ko'paytirish.
-18-5x=20x\times \frac{3}{5}-5\times 9
-18 olish uchun 12 dan 30 ni ayirish.
-18-5x=12x-5\times 9
12 hosil qilish uchun 20 va \frac{3}{5} ni ko'paytirish.
-18-5x=12x-45
-45 hosil qilish uchun -5 va 9 ni ko'paytirish.
-18-5x-12x=-45
Ikkala tarafdan 12x ni ayirish.
-18-17x=-45
-17x ni olish uchun -5x va -12x ni birlashtirish.
-17x=-45+18
18 ni ikki tarafga qo’shing.
-17x=-27
-27 olish uchun -45 va 18'ni qo'shing.
x=\frac{-27}{-17}
Ikki tarafini -17 ga bo‘ling.
x=\frac{27}{17}
Ikkala surat va maxrajdan manfiy belgini olib tashlash bilan \frac{-27}{-17} kasrini \frac{27}{17} ga soddalashtirish mumkin.
