104=1/2[(360-x)-x]


You might want to get rid of the fraction by multiplying both sides by the LCD which is obviously 2:
2*104 = 2*(1/2)[(360-x)-x]
208 = [360 - x - x]
208 = 360 - 2x


Subtract 360 from each side:
208 - 360 = -2x
-152 = -2x


Divide both sides by -2
{{{(-152)/(-2) = (-2x)/(-2)}}}
{{{76 = x}}}
