Graph both equations 3x-2 and 5^(x-1) separately and see where is the intersection, the intersection is where they are equal

Explanation:

enter image source here

The intersection is at x=color(red)1 and x=color(blue)1.707 which seems to be color(blue)(1+sqrt2/2)

These two x values are your solution

Note:-
*I used the app "Desmos graphing calculator" on (iPad) iOS 10 to graph the functions
