0 = (8cos + -3cosx)

Solving
0 = 8cos + -3cosx

Solving for variable 'c'.

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

Add '-8cos' to each side of the equation.
0 + -8cos = 8cos + -8cos + -3cosx
Remove the zero:
-8cos = 8cos + -8cos + -3cosx

Combine like terms: 8cos + -8cos = 0
-8cos = 0 + -3cosx
-8cos = -3cosx

Add '3cosx' to each side of the equation.
-8cos + 3cosx = -3cosx + 3cosx

Combine like terms: -3cosx + 3cosx = 0
-8cos + 3cosx = 0
