1-\frac{1-\frac{x}{2}}{-1}=0
Divide 2 by 2 to get 1.
1-\left(-1-\left(-\frac{x}{2}\right)\right)=0
Anything divided by -1 gives its opposite. To find the opposite of 1-\frac{x}{2}, find the opposite of each term.
1-\left(-1\right)-\left(-\left(-\frac{x}{2}\right)\right)=0
To find the opposite of -1-\left(-\frac{x}{2}\right), find the opposite of each term.
1+1-\left(-\left(-\frac{x}{2}\right)\right)=0
The opposite of -1 is 1.
2-\left(-\left(-\frac{x}{2}\right)\right)=0
Add 1 and 1 to get 2.
-\left(-\left(-\frac{x}{2}\right)\right)=-2
Subtract 2 from both sides. Anything subtracted from zero gives its negation.
-\left(-1\right)\times \frac{x}{2}=\frac{-2}{-1}
Divide both sides by -1.
-\left(-1\right)\times \frac{x}{2}=2
Fraction \frac{-2}{-1} can be simplified to 2 by removing the negative sign from both the numerator and the denominator.
-\frac{x}{2}=-2
Divide both sides by -1.
\frac{x}{2}=\frac{-2}{-1}
Divide both sides by -1.
\frac{x}{2}=2
Fraction \frac{-2}{-1} can be simplified to 2 by removing the negative sign from both the numerator and the denominator.
x=2\times 2
Multiply both sides by 2.
x=4
Multiply 2 and 2 to get 4.
