Solution for 0=(2x)(cos(x))-x equation:


Simplifying
0 = (2x)(cos(x)) + -1x

Remove parenthesis around (2x)
0 = 2x(cos(x)) + -1x

Multiply cos * x
0 = 2x(cosx) + -1x

Multiply x * cosx
0 = 2cosx2 + -1x

Solving
0 = 2cosx2 + -1x

Solving for variable 'c'.

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

Add '-2cosx2' to each side of the equation.
0 + -2cosx2 = 2cosx2 + -2cosx2 + -1x
Remove the zero:
-2cosx2 = 2cosx2 + -2cosx2 + -1x

Combine like terms: 2cosx2 + -2cosx2 = 0
-2cosx2 = 0 + -1x
-2cosx2 = -1x

Divide each side by '-2osx2'.
c = 0.5o-1s-1x-1

Simplifying
c = 0.5o-1s-1x-1
