How do you solve abs(2x-4)=0?

May 20, 2018

$x = 2$

Explanation:

$\left\mid 2 x - 4 \right\mid = 0$

$2 x - 4 = \pm 0$

but since $\pm 0 = 0$ we only need solve:

$2 x - 4 = 0$

$2 x = 4$

$x = 2$

had the equation been equal to something other than zero we would have to solve both the positive and the negative result.
