Roinn

4x\left(1+\frac{12}{25}\right)^{t}=19
Laghdaigh an codán \frac{48}{100} chuig na téarmaí is ísle trí 4 a bhaint agus a chealú.
4x\times \left(\frac{37}{25}\right)^{t}=19
Suimigh 1 agus \frac{12}{25} chun \frac{37}{25} a fháil.
4\times \left(\frac{37}{25}\right)^{t}x=19
Tá an chothromóid i bhfoirm chaighdeánach.
\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}}
Roinn an dá thaobh faoi 4\times \left(\frac{37}{25}\right)^{t}.
x=\frac{19}{4\times \left(\frac{37}{25}\right)^{t}}
Má roinntear é faoi 4\times \left(\frac{37}{25}\right)^{t} cuirtear an iolrúchán faoi 4\times \left(\frac{37}{25}\right)^{t} ar ceal.
x=\frac{19\times \left(\frac{25}{37}\right)^{t}}{4}
Roinn 19 faoi 4\times \left(\frac{37}{25}\right)^{t}.
