Question

Snow+snow+snow=30Snow+stick+stick=20Stick+2glass+2glass=9Stick+1glass+snow=?

Answer 1

Stick =5
1 glass =1
snow=10
5+1+10= 16

Answer 2

3x = 30
x = 10

x + 2y = 20
10 + 2y = 20
2y = 10
y = 5

y + 4z = 9
5 + 4z = 9
4z = 4
z = 1

y + z + x
5 + 1 + 10
6 + 10
16

x = snow
y = stick
z = glass
