Answer:
Crescent = 3, drop = 6, heart = 3, square = 0
Explanation:
Assign each symbol a variable and set up an equation
Crescent = a
Drop = b
Heart = c
Square = d
There’s a few different ones we can set up here
2b + d = b + 2a
2a + 3b + d = c + a + 2b
a + c = b
2b + d = b + 2a can be simplified to
b + d = 2a we can do something with this and a + c = b
a = b - c
d = 2a - b
c = b - a
b = a + c
If you work out this system of equation you get the answer at the top
