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.

oh thanks, i forgot it was multiplication, i added instead. thanks so much for that!
