Dylan has $2.30 in dimes and nickels. The dimes exceed nickels by 5. Find the# of each kind.
let x= nickels=
Let x+5= dimes=
2.3=(.05)x+(.10)x+5
2.3= .05x+.10x+5.1
2.3=.15x+5.1
-2.8= .15x
-18.666666666repeating=x
what did i do wrong?

You forgot confused the parentheses.

2.3 = .05x + .10(x + 5)

2.3 = .05x + .10x +.50

1.8 = .15x

12 = x

I hope this helps. Thanks for asking.
