Solving for variable 'c'.

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

Add '-1' to each side of the equation.
1 + cosx3 + -1 + insx2 = 0 + -1

Reorder the terms:
1 + -1 + cosx3 + insx2 = 0 + -1

Combine like terms: 1 + -1 = 0
0 + cosx3 + insx2 = 0 + -1
cosx3 + insx2 = 0 + -1

Combine like terms: 0 + -1 = -1
cosx3 + insx2 = -1

Add '-1insx2' to each side of the equation.
cosx3 + insx2 + -1insx2 = -1 + -1insx2

Combine like terms: insx2 + -1insx2 = 0
cosx3 + 0 = -1 + -1insx2
cosx3 = -1 + -1insx2

Divide each side by 'osx3'.
c = -1o-1s-1x-3 + -1ino-1x-1

Simplifying
c = -1o-1s-1x-3 + -1ino-1x-1

Reorder the terms:
c = -1ino-1x-1 + -1o-1s-1x-3
