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= .05x+.10x+5.1
-2.8= .15x
what did i do wrong?

  • Algebra -

    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.
