I have the following formula that I need Excel to solve for different values
of P6 ( I have different values of P6 (P7, P8, P9 (reference cells)). I need
the value of x for the different values of P6. Is this possible? It seems
like it should be but I can't find out how to make Excel do this. Please
help! Thanks.

70000 = P6*((((x/80)*(1/5280))*(2/3))+(((x/40)*(1/5280))*(1/3)))
