Unknown variables question
I have a math query relating to a calculation I'm required to do on a property auction website. Apologies if this is the incorrect forum but my understanding of different types of math is quite lacking!
I have the following equation:
w = 200,000
x = 5% of 200,000
y = 17.5% of x
z = x + y
w + z = a
I now need to reverse this equation.
m = w + z. m is known, w and z are unknown.
Both variables to the right of the = are unknown but the percentages are constant, even so, surely this is impossible?
Thanks in advance,
