Reorder the terms for easier multiplication:

4 * 10cos * x + 2 = 2

Multiply 4 * 10

40cos * x + 2 = 2

Multiply cos * x

40cosx + 2 = 2

Reorder the terms:

2 + 40cosx = 2

Add '-2' to each side of the equation.

2 + - 2 + 40cosx = 2 + - 2

Combine like terms: 2 + - 2 = 0

0 + 40cosx = 2 + - 2

40cosx = 2 + - 2

Combine like terms: 2 + - 2 = 0

40cosx = 0

Solving

40cosx = 0

Solving for variable 'c'.

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

Divide each side by '40'.
