A limestone statue is 56 years older than a marble statue. In 12 years, the limestone will be three times as old as the marble statue.

Question

Stupid equation refuses to set up right

Answer 1

L = M + 56

 

L +12 = 3 (M + 12)

 

M + 56 + 12 = 3M + 36

 

2M = 32

 

M = 16 and L = 72

 

In 12 years, M = 28 and L = 84  (84 / 28 = 3)
