from the first line: the star and diamond are the same from the last line: the star multiplied by the diamond is 25 Hence the value of the star is equal to that of the diamond which is the root of 25 = 5 At this point we have: - star = 5 - diamond = 5
using the above two values, from the second line: (5+5)+triangle=20 10+triangle=20 triangle=20-10 Triangle = 10
