( x + $\frac{1}{4}$ ) - $\frac{3}{4}$ = 5%
( x + $\frac{1}{4}$ ) - $\frac{3}{4}$ = $\frac{1}{20}$
x + $\frac{1}{4}$ = $\frac{1}{20}$ + $\frac{3}{4}$
x + $\frac{1}{4}$ = $\frac{1}{20}$ + $\frac{15}{20}$
x + $\frac{1}{4}$ = $\frac{16}{20}$
x = $\frac{16}{20}$ - $\frac{1}{4}$
x = $\frac{16}{20}$ - $\frac{5}{20}$
x = $\frac{11}{20}$

Giải thích các bước giải:
| x + `1/4` | - `3/4` = 5%
⇒ | x + `1/4` | = `1/20` + `3/4` = `4/5`
⇒ x + `1/4` = `4/5` hay x + `1/4` = `-4/5`
⇒ x = `11/20` hay x = `-21/20`
