Fie x - nr. de mere
a = 3*x/6 = x/2
r1 = x - x/2 = x/2
b = 6*r1/12 = r1/2 = x/4
r2 = x/2 - x/4 = x/4
c = r2/3 + 4 = x/12 + 4
r3 = x/4 - x/12 - 4 = 3x/12 - x/12 - 4 = x/6 - 4
d = r3/2 + 2 = x/12 - 2 + 2 = x/12
e = 8
x = a + b + c + d + e
x = x/2 + x/4 + x/12 + 4 + x/12 + 8
x = 6x/12 + 3x/12 + 2x/12 + 12
12x/12 = 11x/12 + 12
x/12 = 12
x = 12 * 12 = 144
