heheh you need to explain
how you get it

The post said not to give hints...But yes I looked at the set of numbers equaling 32 and 36. I noticed the set has green hearts and the difference was 4. Therefore the multiplication had to be by multiples of 4. So i thought 4x=36 and 4x=32 so .....(4x)/4=36/4....x=9 for blue heart.(4x)/4=32/4....x=8 for red heart. Now to check my answer I multiplied the value of the blue heart(9) by the value of the red heart(8) and got 72. Thus the value of the green heart must be 4.
