4x\left(1+\frac{12}{25}\right)^{t}=19
\frac{48}{100} ulushini 4 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.
4x\times \left(\frac{37}{25}\right)^{t}=19
\frac{37}{25} olish uchun 1 va \frac{12}{25}'ni qo'shing.
4\times \left(\frac{37}{25}\right)^{t}x=19
Tenglama standart shaklda.
\frac{4\times \left(\frac{37}{25}\right)^{t}x}{4\times \left(\frac{37}{25}\right)^{t}}=\frac{19}{4\times \left(\frac{37}{25}\right)^{t}}
Ikki tarafini 4\times \left(\frac{37}{25}\right)^{t} ga bo‘ling.
x=\frac{19}{4\times \left(\frac{37}{25}\right)^{t}}
4\times \left(\frac{37}{25}\right)^{t} ga bo'lish 4\times \left(\frac{37}{25}\right)^{t} ga ko'paytirishni bekor qiladi.
x=\frac{19\times \left(\frac{25}{37}\right)^{t}}{4}
19 ni 4\times \left(\frac{37}{25}\right)^{t} ga bo'lish.
