Answer:

x=-2.531

Step-by-step explanation:

we have

$-2x-3=3^{x} +2$

we can divide the expression above into two equations

$y=-2x-3$ --->equation A

$y=3^{x} +2$ ----> equation B

The solution of the original expression is the same that the x-coordinate of the intersection point both graphs

using a graphing tool

The intersection point is (-2.531,2.062)

see the attached figure

therefore

The solution is x=-2.531
