I think the problem may have a typo. It works out nicely if the second term on the RHS is 3^(x+1) instead of 3^(x-1)

in the original problem the solution couldnt be expressed in a closed form, and I had to solve it numerically

even lambert W didnt help

it is likely a mistake in the question if its a school problem
