Solving
400 = 20e3x

Solving for variable 'e'.

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

Add '-20e3x' to each side of the equation.
400 + -20e3x = 20e3x + -20e3x

Combine like terms: 20e3x + -20e3x = 0
400 + -20e3x = 0

Add '-400' to each side of the equation.
400 + -400 + -20e3x = 0 + -400

Combine like terms: 400 + -400 = 0
0 + -20e3x = 0 + -400
-20e3x = 0 + -400

Combine like terms: 0 + -400 = -400
-20e3x = -400

Divide each side by '-20x'.
e3 = 20x-1

Simplifying
e3 = 20x-1

Combine like terms: 20x-1 + -20x-1 = 0
e3 + -20x-1 = 0
