\left(x-6\right)\times 5-\left(2x+1\right)\times 2=4
x qiymati -\frac{1}{2},6 qiymatlaridan birortasiga teng bo‘lmaydi, chunki nolga bo‘lish mumkin emas. Tenglamaning ikkala tarafini \left(x-6\right)\left(2x+1\right) ga, 2x+1,x-6,2x^{2}-11x-6 ning eng kichik karralisiga ko‘paytiring.
5x-30-\left(2x+1\right)\times 2=4
x-6 ga 5 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
5x-30-\left(4x+2\right)=4
2x+1 ga 2 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
5x-30-4x-2=4
4x+2 teskarisini topish uchun har birining teskarisini toping.
x-30-2=4
x ni olish uchun 5x va -4x ni birlashtirish.
x-32=4
-32 olish uchun -30 dan 2 ni ayirish.
x=4+32
32 ni ikki tarafga qo’shing.
x=36
36 olish uchun 4 va 32'ni qo'shing.
