Identical expressions
u+v*e^(5x)= two ; 5v*e^(5x)= one
u plus v multiply by e to the power of (5x) equally 2; 5v multiply by e to the power of (5x) equally 1
u plus v multiply by e to the power of (5x) equally two ; 5v multiply by e to the power of (5x) equally one
u+v*e(5x)=2; 5v*e(5x)=1

       5*x    
u + v*E    = 2

$$u + e^{5 x} v = 2$$

     5*x    
5*v*E    = 1

$$e^{5 x} 5 v = 1$$

E^(5*x)*(5*v) = 1

Rapid solution

$$v_{1} = \frac{e^{- 5 x}}{5}$$
=
$$\frac{e^{- 5 x}}{5}$$
=

0.2*exp(-5*x)

$$u_{1} = \frac{9}{5}$$
=
$$\frac{9}{5}$$
=
