+68 The denominator of a fraction is 2 more than its numerator.
When 1212 is added to this fraction, the resulting fraction's denominator is twice the denominator of the original fraction and its numerator is 1 more than its denominator.
What is the numerator of the original fraction?
How to do this?
Thanks for the tips guys

+37146 x / (x+2) + 1/2 = ( 2(x+2) +1)/ (2(x+2)) cross multiply L side
(2x + 2 + x )/(2(x+2)) = (2x+4 +1) / (2(x+2) eliminate the denominators
3x+2 = 2x+5
x=3
fraction is 3/5
3/5 + 1/2 = 6/10 + 5/10 = 11/10 Check!
+129852 x / [ x + 2 ] + 12 = [ x + 3 ] / ( 2 [ x + 2 ] ) simplify
[ x + 12 (x + 2) ] / [ x + 2] = [ x + 3 ] / ( 2 [ x + 2] )
x + 12x + 24 = [ x + 3 ] / 2
13x + 24 = [ x + 3 ] / 2 cross-multiply
26x + 48 = x + 3 simplify
25x = - 45
x = - 45 / 25 = - 9 / 5 = original numerator
