Here add squares with squares ,and circles with circles.
then there are 3 squares with an x , so this represents 3x
there are two circles with an 1 inside. So this represents 2
Now in the right part we have 5 boxes and 8 circles
this represents 5x + 8
then the total equation is
3x + 2 = 5x + 8
now agrupating similars we obtain
(3x-5x) = ( 8-2)
-2x = 6 then finally x= -3
