Step 1.1

Cancel the common factor.

$\frac{- 7 e^{- 0.1 t}}{- 7} = - 1$

Step 1.2

Divide $e^{- 0.1 t}$ by $1$ .

$e^{- 0.1 t} = - 1$

Step 2

Solve for $t$ .

Step 2.1

Take the natural logarithm of both sides of the equation to remove the variable from the exponent.

$\ln (e^{- 0.1 t}) = \ln (- 1)$

Step 2.2

The equation cannot be solved because $\ln (- 1)$ is undefined.

Undefined

Step 2.3

There is no solution for $e^{- 0.1 t} = - 1$

No solution
