# Core 2 Logs Question watch

1. Question:

2^(x-1) = 3^(x+1)

I have attempted this question, I have got to:

(x-1)log2 = (x+1)log3

After this step I can't seem to get anywhere near to solving for x.

I've tried multiplying out the brackets, but I'm not sure where to go after this first step.

Hopefully someone could guide me to the solution, thanks in advance.

Multiplying out the brackets then collecting the x terms on one side of the equality is the way forward.
