The mathematics club in a school has 53 members. 5/7 of the girls members and 3/5 of the boys members are from lower secondary. The total number of lower secondary members is 35. How many members of the club are boys?

5 answers

X girls in the class.
(53-x) boys in the class.

5x/7 + 3/5(53-x) = 35.
25x + 21(53-x) = 1225.
25x + 1113-21x = 1225.
4x = 112, X = 28.

53-28 = 25 Boys in the class.

right

By the way I have d1 and in the answers it says that 25 members are boys not 28
