Solving
2 = 2kx

Solving for variable 'k'.

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

Add '-2kx' to each side of the equation.
2 + -2kx = 2kx + -2kx

Combine like terms: 2kx + -2kx = 0
2 + -2kx = 0

Add '-2' to each side of the equation.
2 + -2 + -2kx = 0 + -2

Combine like terms: 2 + -2 = 0
0 + -2kx = 0 + -2
-2kx = 0 + -2

Combine like terms: 0 + -2 = -2
-2kx = -2

Divide each side by '-2x'.
k = x-1

Simplifying
k = x-1
