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?

**PsyDAG**, Saturday, October 27, 2007 at 1:02pmYou 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.
