Circle+box =39 (Equation 2)
In the above two formulas, there are boxes. You can subtract 33 from 39 to find out the difference between a circle and a triangle.
39-33= circle-triangle
6= circle-triangle
Triangle +6= circle (Equation 3)
Triangle+circle =34, if it is brought into Equation 3, it becomes:
Triangle+triangle +6=34
2 triangles =34-6
=28
Triangle = 14
Box =33- 14
= 19
Circle =39- 19
=20
