Six percent of one number diminished by one percent of another leaves 9.
.06x-.01y=9
You didn't solve that for x correctly.
Multiply through by 100
6x-y=900
You should solve that for y, not x
6x-900=y
the equation for the second sentence:
Five percent of the first increased by 3 percent of the second equals 19.
.05x-.03y=19
Multiply that through by 100
5x-3y=1900
Now substitute 6x-900 for y in that and you'll get it.
If you have trouble tell me in the thank-you note form below, and
