Question 86523
Question:

{{{ ( 5x/(x-7) )- (35 /(x-7))}}}

Answer:


{{{ ( 5x/(x-7) ) - (35 /(x-7))}}} = {{{ ( 5x/(x-7) ) - (35 /(x-7))}}}



Here the denominators are same...so you can directly subtract the numerators...


==> {{{ (5x - 35 )/ (x - 7 )}}}



Take our common term of the numnerator....



==> {{{ 5 (x - 7 )/ (x - 7 )}}}



Now you have (x-7) is common in both the numeraor and the denominator..


So it will get cancelled....


==> answer is 5




That is    {{{ ( 5x/(x-7) )- (35 /(x-7))}}}  = 5




Hope you found the explanation useful....
