ex=9+x+5
Calculate 3 to the power of 2 and get 9.
ex=14+x
Add 9 and 5 to get 14.
ex-x=14
Subtract x from both sides.
\left(e-1\right)x=14
Combine all terms containing x.
\frac{\left(e-1\right)x}{e-1}=\frac{14}{e-1}
Divide both sides by e-1.
x=\frac{14}{e-1}
Dividing by e-1 undoes the multiplication by e-1.
