Triangle + 2 = Square
Hexagon + 1 = Square
2 Triangle + 2 Square = 28
28/4 = 7
If (1st row): 7 + 1 = Square
Square = 8
Then Triangle = 6
Then (2nd row):8 x 2 = 16
30 - 16 = 14
14/2 = Hexagon
Hexagon = 7
Then (3rd row) : 20 - 8 (square) = 12
12/3 = 4
Circle = 4

The then far left row : (2 x 4) + 7 + 6 = 21
? = 21
