Question 439897
the denominator {{{y}}} is 4 less than the numerator {{{x}}}. 


{{{x/y=x/(x+4)}}}


If 3 is added to both the numerator and the denominator,the resulting fraction is equivalent to 3/3.  

{{{(x+3)/(x+4+3)=3/3}}}

{{{(x+3)/(x+7)=3/3}}}..cross multiply

{{{3(x+3)=3(x+7)}}}


{{{3x+9=3x+21)}}}

{{{3x-3x=21-9)}}}...........{{{x}}} cancels; so, there is no solution
