Can you figure out how to make the balance even?
If 2 diamonds = 1 circle and 2 squares = 3 circles, what do you need to
balance out 1 square?

balance out 1 square?
Equations to solve problem:
If 2 d = 1 c and 2 s = 3 c then 2 s = 3(2 d)2 s = 6 d, or 1 s = 3 d
1s = (d + d) + d, therefore 1s = (1c) + d
