Question

i am thinking of a number. if you multiply it by 7, then add 15, and finally subtract 3^2 you get 48. write and solve an equation that describes the number (x) that i am thinking of.


how do i find it?
what is x?

Answer 1

Let 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
