Multiple Choice

Solve the equation. Write the solution set with the exact values given in terms of natural or common
logarithms. Also give approximate solutions to 4 decimal places, if necessary.
- $$e ^ { 7 x } = - 9 e ^ { 2 x }$$

A) $\left\{ \frac { \ln 9 } { 5 } \right\} ; x \approx 2.2756$
B) $\left\{ \frac { \ln - 9 } { 5 } \right\} ; x \approx 2.2756$
C) $\left\{ \frac { \ln 9 } { - 5 } \right\} ; x \approx - 2.2756$
D) \{ \}
