2(

*x*- 3) = 8 (what we're given)*x*- 3 = 4 (divide both sides by 2)

*x*= 7 (add 3 to both sides)

Now we just need to put 7 in for

*x*in the expression:(

*x*- 3)/(*x*+ 3)(7 - 3)/(7 + 3) (substitute 7 for

*x*)**4/10**

We can grid in our answer as 0.4, 4/10, 2/5, etc. Me? I prefer to use decimals.
