Sam and Sue have only nickels and dimes. Sue has 35¢. Sam has the same number of dimes as Sue has nickels, and he has half as many nickels as Sue has dimes. How many nickels does Sue have?

please help me with this question
If Sue has d dimes and n nickels, then
10d + 5n = 35
d=1 and n=5
or d=2 and n=3
or d=3 and n=1
Since Sam has d/2 nickels, d must be even.
So Sue has 3 nickels
10d + 5n = 35
d=1 and n=5
or d=2 and n=3
or d=3 and n=1
Since Sam has d/2 nickels, d must be even.
So Sue has 3 nickels
