Solution for 200=400-e^3t equation:


Simplifying
200 = 400 + -1e3t

Solving
200 = 400 + -1e3t

Solving for variable 'e'.

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

Add 'e3t' to each side of the equation.
200 + e3t = 400 + -1e3t + e3t

Combine like terms: -1e3t + e3t = 0
200 + e3t = 400 + 0
200 + e3t = 400

Add '-200' to each side of the equation.
200 + -200 + e3t = 400 + -200

Combine like terms: 200 + -200 = 0
0 + e3t = 400 + -200
e3t = 400 + -200

Combine like terms: 400 + -200 = 200
e3t = 200

Divide each side by 't'.
e3 = 200t-1

Simplifying
e3 = 200t-1

Combine like terms: 200t-1 + -200t-1 = 0
e3 + -200t-1 = 0

Factor out the Greatest Common Factor (GCF), 't-1'.
t-1(e3t + -200) = 0

Subproblem 1

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