os2xC + -1 * -1ens * x = sen2x + 1

Multiply -1 * -1
os2xC + 1ens * x = sen2x + 1

Multiply ens * x
os2xC + 1ensx = sen2x + 1

Reorder the terms:
1ensx + os2xC = sen2x + 1

Reorder the terms:
1ensx + os2xC = 1 + en2sx

Solving
1ensx + os2xC = 1 + en2sx

Solving for variable 'e'.

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

Add '-1en2sx' to each side of the equation.
1ensx + -1en2sx + os2xC = 1 + en2sx + -1en2sx

Combine like terms: en2sx + -1en2sx = 0
1ensx + -1en2sx + os2xC = 1 + 0
1ensx + -1en2sx + os2xC = 1

Add '-1os2xC' to each side of the equation.
1ensx + -1en2sx + os2xC + -1os2xC = 1 + -1os2xC

Combine like terms: os2xC + -1os2xC = 0
1ensx + -1en2sx + 0 = 1 + -1os2xC
1ensx + -1en2sx = 1 + -1os2xC

Reorder the terms:
-1 + 1ensx + -1en2sx + os2xC = 1 + -1os2xC + -1 + os2xC

Reorder the terms:
-1 + 1ensx + -1en2sx + os2xC = 1 + -1 + -1os2xC + os2xC

Combine like terms: 1 + -1 = 0
-1 + 1ensx + -1en2sx + os2xC = 0 + -1os2xC + os2xC
-1 + 1ensx + -1en2sx + os2xC = -1os2xC + os2xC

Combine like terms: -1os2xC + os2xC = 0
-1 + 1ensx + -1en2sx + os2xC = 0
