Number of marbles that Valen had before = 9 u
Number of marbles that Valen gave to Sam = 2 u
Number of marbles that Valen gave to Pierre = 2 u
Number of marbles that Valen gave to Vincent = 3 u
Number of marbles that Valen had left = 2 u
2 u = 38
1 u = 38 ÷ 2 = 19
Number of marbles that Valen had at first
= 9 u
= 9 u x 19
= 171
