Solution for 20=100e^8y equation:


Simplifying
20 = 100e8y

Solving
20 = 100e8y

Solving for variable 'e'.

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

Add '-100e8y' to each side of the equation.
20 + -100e8y = 100e8y + -100e8y

Combine like terms: 100e8y + -100e8y = 0
20 + -100e8y = 0

Add '-20' to each side of the equation.
20 + -20 + -100e8y = 0 + -20

Combine like terms: 20 + -20 = 0
0 + -100e8y = 0 + -20
-100e8y = 0 + -20

Combine like terms: 0 + -20 = -20
-100e8y = -20

Divide each side by '-100y'.
e8 = 0.2y-1

Simplifying
e8 = 0.2y-1

Combine like terms: 0.2y-1 + -0.2y-1 = 0.0
e8 + -0.2y-1 = 0.0

Factor out the Greatest Common Factor (GCF), 'y-1'.
y-1(e8y + -0.2) = 0.0

Subproblem 1

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

Subproblem 2

Set the factor '(e8y + -0.2)' equal to zero and attempt to solve: Simplifying e8y + -0.2 = 0 Reorder the terms: -0.2 + e8y = 0 Solving -0.2 + e8y = 0 Move all terms containing e to the left, all other terms to the right. Add '0.2' to each side of the equation. -0.2 + 0.2 + e8y = 0 + 0.2 Combine like terms: -0.2 + 0.2 = 0.0 0.0 + e8y = 0 + 0.2 e8y = 0 + 0.2 Combine like terms: 0 + 0.2 = 0.2 e8y = 0.2 Divide each side by 'y'. e8 = 0.2y-1 Simplifying e8 = 0.2y-1 The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined. The solution to this equation could not be determined.
