Simplifying
12 + -1e2t = 9

Solving
12 + -1e2t = 9

Solving for variable 'e'.

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

Add '-12' to each side of the equation.
12 + -12 + -1e2t = 9 + -12

Combine like terms: 12 + -12 = 0
0 + -1e2t = 9 + -12
-1e2t = 9 + -12

Combine like terms: 9 + -12 = -3
-1e2t = -3

Divide each side by '-1t'.
e2 = 3t-1

Simplifying
e2 = 3t-1

Combine like terms: 3t-1 + -3t-1 = 0
e2 + -3t-1 = 0

Factor out the Greatest Common Factor (GCF), 't-1'.
t-1(e2t + -3) = 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.

Subproblem 2

Set the factor '(e2t + -3)' equal to zero and attempt to solve: Simplifying e2t + -3 = 0 Reorder the terms: -3 + e2t = 0 Solving -3 + e2t = 0 Move all terms containing e to the left, all other terms to the right. Add '3' to each side of the equation. -3 + 3 + e2t = 0 + 3 Combine like terms: -3 + 3 = 0 0 + e2t = 0 + 3 e2t = 0 + 3 Combine like terms: 0 + 3 = 3 e2t = 3 Divide each side by 't'. e2 = 3t-1 Simplifying e2 = 3t-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.
