**Trig**, Thursday, November 13, 2008 at 10:34pmLet x be the number.

You multiply that number by 7

SO FAR WE HAVE: 7x

You add 15 to that number

SO FAR WE HAVE: 7x+15

You subtract 3^2 (which is 9) from that number

SO FAR WE HAVE: 7x+15-9

When you do all of that to the number, you get 48

THE FINAL EQUATION IS: 7x+15-9=48

TO SOLVE:

7x+6=48

7x=42

x=6
