Homework Statement

I am just stuck on a step in my problem , I have found the solution but have been attempting rearrange the equation but I just don't get it. Its probably a simple step

Homework Equations

0=x[(tanα-tanθ)-(gx/2Vo^2Cos^2(α)]

then this forms into this

x=(tanα-tanθ/g)(2Vo^2Cos^2(α))

The Attempt at a Solution

How do you get the X to the other side. There is a parentheses next to the x so you can divide anything out?
