The answer would be 8 132/999. I don't know if you can simplify it but see if you can.
Let x = first number and y = second number.
The first statement is expressed as
x*y = 713
The second statement is expressed as
x = y + 9
To find x, use the second equation in terms of y, that is y = x - 9. Then substituting it to the first equation yields
x*(x - 9) = 713
y+2=-3x+12
-2 -2
y=-3x+10
This is as far as it can be simplified.

First you ask yourself, can 8 go into 1? The answer is no. Can 8 go into 12? Yes, 1 time. So you put 1 on top of the 2 and subtract 8 from 12. That gives you 4. Then you pull down the 8 from 128 and ask how many times can 8 go into 48? The answer is 6. So your answer is 16. Hope I helped!
