In an integration exercise, I'm trying to find the points of intersection for two functions. The two functions are:

d(x) = 3^x

f(x) = -2x+5

I set them to being equal, and then took the log of both sides. (The x exponent on 3^x jumps in front because of the logarithm identities)

3^x = -2x+5

xlog3 = log(-2x+5)

Now I am stuck, and I'm not sure of what to do. I would really appreciate anybody's assistance.
