what is the answer of this question.

John has 4 more nickels than dimes in his pocket, for a total of $1.25.Which equation could be used to determine the number of dimes,X, in his pocket.

Michael P.

X = number of dimes in pocket
Y = number of nickels in pocket
 Y = X +4
convert money to cents
5 x Y + 10 x X = 125
5 x (X + 4) + 10 x X = 125
5 x X + 20 + 10 x X =125
15 x X = 105
X = 105/15 = 7 dimes
Y = X + 4 = 7 + 4 = 11 nickels
