At first i tried the 3rd colum going across and i did trial and error for the circle i found out that the circle is 4. 4x3=12 and that means the triangle is has to be 6 making the 3rd row across is 18. After that i checked the top row across and if triangle is 6 the 2 triangles make 12 because there was 2 squares left and the remaining number was 14 so 14 divided by 2 (squares) equals 7 so the square had to be 7. I then checked the third row down which has 1 square 2 circles and 1 hexagon 1 circle is 4 so 4x2=8 and 1 square which is 8 so then 8+8=16 and the remaining number was 7 so the equal was 23

Circle = 4

Square = 8

Triangle = 6

Hexangon = 7

? = 21
