.10(x)=dimes
.05(x+44)=29.50
.15x+44=29.50
15x=-14.50
x=-96.666
I keep getting a negative number am I doing something wrong?

The issue occurs when you distribute.

When you go from .05(x+44) to .15x+44 it is NOT correct.

You forgot to multiply 0.05 by 44 to get 2.2

.05 * x IS NOT:   .15x

.05 * 44 IS NOT:   44

You need to do correct computations!! If not you will always be WRONG!!
