Answer:

Step-by-step explanation:
![(e^x)'=e^x\\\\\bigg[f\bigg(g(x)\bigg)\bigg]'=f'\bigg(g(x)\bigg)\cdot g'(x)\\\\\left(\dfrac{1}{x}\right)'=-\dfrac{1}{x^2}\\\\====================](https://tex.z-dn.net/?f=%28e%5Ex%29%27%3De%5Ex%5C%5C%5C%5C%5Cbigg%5Bf%5Cbigg%28g%28x%29%5Cbigg%29%5Cbigg%5D%27%3Df%27%5Cbigg%28g%28x%29%5Cbigg%29%5Ccdot%20g%27%28x%29%5C%5C%5C%5C%5Cleft%28%5Cdfrac%7B1%7D%7Bx%7D%5Cright%29%27%3D-%5Cdfrac%7B1%7D%7Bx%5E2%7D%5C%5C%5C%5C%3D%3D%3D%3D%3D%3D%3D%3D%3D%3D%3D%3D%3D%3D%3D%3D%3D%3D%3D%3D)

" the difference " means subtract
3n - 4 = -19 <== ur equation
3n = -19 + 4
3n = - 15
n = -15/3
n = -5 <== ur number
