Answer:

Option D. x=-2.5

Explanation:

we have


-2x-3=3^x+2

I can divide the expression above in a system of two equations


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


y=3^x+2 ----> equation B

Solve by graphing

The solution is equal to the x-coordinate of the intersection point both graphs

using a graphing tool

The intersection point is ( -2.5,2.1)

see the attached figure

therefore

The solution is x=-2.5
