\frac{2}{5}x+4+4x=0
4x ni ikki tarafga qo’shing.
\frac{22}{5}x+4=0
\frac{22}{5}x ni olish uchun \frac{2}{5}x va 4x ni birlashtirish.
\frac{22}{5}x=-4
Ikkala tarafdan 4 ni ayirish. Har qanday sonni noldan ayirsangiz, o‘zining manfiyi chiqadi.
x=-4\times \frac{5}{22}
Ikki tarafini \frac{5}{22} va teskari kasri \frac{22}{5} ga ko‘paytiring.
x=\frac{-4\times 5}{22}
-4\times \frac{5}{22} ni yagona kasrga aylantiring.
x=\frac{-20}{22}
-20 hosil qilish uchun -4 va 5 ni ko'paytirish.
x=-\frac{10}{11}
\frac{-20}{22} ulushini 2 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.
