Solving
280 = 40 + 30e2x

Solving for variable 'e'.

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

Add '-30e2x' to each side of the equation.
280 + -30e2x = 40 + 30e2x + -30e2x

Combine like terms: 30e2x + -30e2x = 0
280 + -30e2x = 40 + 0
280 + -30e2x = 40

Add '-280' to each side of the equation.
280 + -280 + -30e2x = 40 + -280

Combine like terms: 280 + -280 = 0
0 + -30e2x = 40 + -280
-30e2x = 40 + -280

Combine like terms: 40 + -280 = -240
-30e2x = -240

Divide each side by '-30x'.
e2 = 8x-1

Simplifying
e2 = 8x-1

Combine like terms: 8x-1 + -8x-1 = 0
e2 + -8x-1 = 0

Factor out the Greatest Common Factor (GCF), 'x-1'.
x-1(e2x + -8) = 0

Subproblem 1

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