I have a simple single variable algebra formula that I can't seem to solve using the Solver function. It's not a homework problem, but a formula that I'd like to be able to solve repeatedly and quickly using different inputs.

The formula is: A1 = (1/A2)*A3+(A4/((1+A2)-g))

A1 through A4 all have values in the cells, e.g.:
A1=15
A2=0.10
A3=0.48
A4=0.12

solving for g
