Simplifying
Cosx = cosy

Solving
osxC = cosy

Solving for variable 'o'.

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

Add '-1cosy' to each side of the equation.
-1cosy + osxC = cosy + -1cosy

Combine like terms: cosy + -1cosy = 0
-1cosy + osxC = 0

Factor out the Greatest Common Factor (GCF), 'os'.
os(-1cy + xC) = 0

Subproblem 1

Set the factor 'os' equal to zero and attempt to solve: Simplifying os = 0 Solving os = 0 Move all terms containing o to the left, all other terms to the right. Simplifying os = 0 The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.

Subproblem 2

Set the factor '(-1cy + xC)' equal to zero and attempt to solve: Simplifying -1cy + xC = 0 Solving -1cy + xC = 0 Move all terms containing o to the left, all other terms to the right. Add 'cy' to each side of the equation. -1cy + cy + xC = 0 + cy Combine like terms: -1cy + cy = 0 0 + xC = 0 + cy xC = 0 + cy Remove the zero: xC = cy Add '-1xC' to each side of the equation. xC + -1xC = cy + -1xC Combine like terms: xC + -1xC = 0 0 = cy + -1xC Simplifying 0 = cy + -1xC The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined. The solution to this equation could not be determined.
