Oh okay, sorry,  
I honestly don't know how...

mathstudent55 · Answer

First, isolate the absolute value on the left side.
The absolute value of k is being multiplied by the fraction 2/5.
If you multiply both sides of the equation by the reciprocal of 2/5, which is 5/2, you will end up with just |k| on the left side.
Start there.
Multiply both sides of the equation by 5/2 and show what you get.
