\frac{1}{5}x+2-\frac{3}{7}x=0
Ikkala tarafdan \frac{3}{7}x ni ayirish.
-\frac{8}{35}x+2=0
-\frac{8}{35}x ni olish uchun \frac{1}{5}x va -\frac{3}{7}x ni birlashtirish.
-\frac{8}{35}x=-2
Ikkala tarafdan 2 ni ayirish. Har qanday sonni noldan ayirsangiz, o‘zining manfiyi chiqadi.
x=-2\left(-\frac{35}{8}\right)
Ikki tarafini -\frac{35}{8} va teskari kasri -\frac{8}{35} ga ko‘paytiring.
x=\frac{-2\left(-35\right)}{8}
-2\left(-\frac{35}{8}\right) ni yagona kasrga aylantiring.
x=\frac{70}{8}
70 hosil qilish uchun -2 va -35 ni ko'paytirish.
x=\frac{35}{4}
\frac{70}{8} ulushini 2 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.
