Integration: Finding Area...B Level Question?

I'm supposed to find the area in between

f(x)=ln(3x-2)-1 and g(x)=-4cos(0.5x)+2

I'm ok with finding the integral, but how to find the limits. This equation is pretty impossible to solve, isn't it? The answer says the point of intersection is at x=3.77 and x=8.3, but I'm not sure if I'm supposed to use a graphic calculator to figure this out.

Any help / suggestions appreciated

    The points of intersection are your limits, you need to find the area enclosed between the graphs between these two x values.

    You can find the points of intersection manually using Newton's method or Simpson's, but in the end you are better off sticking with the calculator.
