Question 1148005
The denominator of the fraction is 2 more than the numerator<pre> 

D = N + 2
</pre>
If 1 is subtracted from the numerator 
<pre>
NEW numerator = N-1
</pre>
and 2 is added to the denominator 
<pre>
NEW denominator = D+2
</pre>
the (NEW) numerator becomes half of the (NEW) denominator.
<pre>
NEW numerator = N-1 = (1/2)(D+2) 

Multiply both sides by 2:

             2(N-1) = 2(1/2)(D+2)
               2N-2 = D+2
               2N-D = 4

So we have the system of two equations in two unknowns:

{{{system(D=N+2,2N-D=4)}}}

YOU solve that system for the values of N and D by substitution.
</pre>
find the fraction.
<pre>
Put the original numerator, the value of N, over D, the
value of the denominator.  DO NOT REDUCE THE FRACTION!!!
