Divide 54 books into three groups, one fifth of group A, 25% of group B and half of group C. how many books do group A, B and C get?

Suppose a group x, B group y, C group Z
1/5 x=1/4 y+ 1/2 z (1)
x+y+z=54 (2)
(1) Multiply by 5 and bring in 2
5/4y+7/2z=54
Y and Z are even numbers, and the multiple of Y is 4 and X is 5
Multiple of

You're wrong, right
