# Math Help - TI-89 Titanium: SOLVE AN EQUATION

1. ## TI-89 Titanium: SOLVE AN EQUATION

The equation is this: ln(x-1)=2x-3

When i solve for x, the calculator says: More solutions may exist.

and it does not give me any solutions.

What should i do to get the results?

Graph it.

From the graph, there is no intersection point.

Thus, the solution to the equation you asked about will be complex.

On the TI89, use

Code:
csolve(ln(x-1)=2x-3,x)
You will get 1 solution.

I hope this clarifies things!
