Solving for variable 'c'.

Move all terms containing c to the left, all other terms to the right.

Add '-5insx' to each side of the equation.
cosx + 5insx + -5insx = 0 + -5insx

Combine like terms: 5insx + -5insx = 0
cosx + 0 = 0 + -5insx
cosx = 0 + -5insx
Remove the zero:
cosx = -5insx

Divide each side by 'osx'.
c = -5ino-1

Simplifying
c = -5ino-1
