Chap 4: Algebra Puzzle 3x4





Bug-b
Gift-g
Papaya-p





2g+2b = 102
1g+1b = 51
2b+1g+1p = 93
1b+1p = 93 - 51 = 42
1b+3p = 82
2p = 82 - 42 = 40
p = 20
b = 82 - 20 - 20 - 20 = 22
2b+2g = 102
2g = 102 - 22 - 22 = 58
g = 29

So, b=22, g=29 and p= 20.

Chap 4: Algebra Puzzle 3x3





Pumpkin-p
Gift-g
Star-s





3p = 51
p = 51 ÷ 3 = 17
s+2p = 48
s = 48 - 17 - 17 = 14
s+g+p = 39
g = 39 - 17 - 14 = 8

So, p=17, g=8 and s=14.
