## Homework Statement

3^x + x = 4

solve for x.

## Homework Equations

I'm thinking of using the logarithm laws. log(a.b) = log a + logb log(a/b) = log a - log b

log(a^b) = bloga

## The Attempt at a Solution

Well if I isolate the exponential

3^x = 4-x

take logs on both sides

xlog3 = log(4-x)

I can't seem to get the x out of the log.
