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.
3 + -8cos = 7 + 8cos + -8cos + 16cosx

Combine like terms: 8cos + -8cos = 0
3 + -8cos = 7 + 0 + 16cosx
3 + -8cos = 7 + 16cosx

Add '-16cosx' to each side of the equation.
3 + -8cos + -16cosx = 7 + 16cosx + -16cosx

Combine like terms: 16cosx + -16cosx = 0
3 + -8cos + -16cosx = 7 + 0
3 + -8cos + -16cosx = 7

Add '-3' to each side of the equation.
3 + -8cos + -3 + -16cosx = 7 + -3

Reorder the terms:
3 + -3 + -8cos + -16cosx = 7 + -3

Combine like terms: 3 + -3 = 0
0 + -8cos + -16cosx = 7 + -3
-8cos + -16cosx = 7 + -3

Combine like terms: 7 + -3 = 4
-8cos + -16cosx = 4

Reorder the terms:
-4 + -8cos + -16cosx = 4 + -4

Combine like terms: 4 + -4 = 0
-4 + -8cos + -16cosx = 0

Factor out the Greatest Common Factor (GCF), '-4'.
-4(1 + 2cos + 4cosx) = 0

Ignore the factor -4.
