Solving for x?

[gutharius]

Sorry to make you guys/gals think on a weekend, I need to know how to solve for x here but my pre algebra days are failing my memory.

x-xy=z

x=Before Tax Income (Unknown)
y=Percentage of Before income taxed (Known)
z=After Tax Income (Known)

TIA

x - xy = z
x (1 - y) = z
x = z/(1-y)
