Answer:Simplifying

cos(9x) = 9

Remove parenthesis around (9x)

cos * 9x = 9

Reorder the terms for easier multiplication:

9cos * x = 9

Multiply cos * x

9cosx = 9

Solving

9cosx = 9

Solving for variable 'c'.

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

Divide each side by '9osx'.

c = o-1s-1x-1
