$\frac{(( \frac{x}{2}−\frac{0.5}{2})−0.5)}{2}−0.5=0$。如何求解?
已知:$\frac{( \frac{x}{2}−\frac{0.5}{2})−0.5}{2}−0.5=0$。
求解:$\frac{( \frac{x}{2}−\frac{0.5}{2})−0.5}{2}−0.5=0$。
解答
$\frac{( \frac{x}{2}−\frac{0.5}{2})−0.5}{2}−0.5=0$
$\Rightarrow \frac{( \frac{x-0.5}{2})−0.5}{2}−0.5=0$
$\Rightarrow \frac{( \frac{x-0.5-1}{2})}{2}−0.5=0$
$\Rightarrow \frac{x-1.5}{4}−0.5=0$
$\Rightarrow \frac{x-1.5-2}{4}=0$
$\Rightarrow x-3.5=0$
$\Rightarrow x=3.5$
