7x+8overx+1 + 4x+3overx+1 add if possible simplify
:
%28%287x%2B8%29%2F%28x%2B1%29%29 + %28%284x%2B3%29%2F%28x%2B1%29%29
:
They have the same denominator so can write it:
%28%287x%2B8%29%2B%284x%2B3%29%29%2F%28%28x%2B1%29%29
:
%287x+%2B+4x+%2B+8+%2B+3%29%2F%28%28x%2B1%29%29; remove brackets, group like terms
:
%2811x+%2B+11%29%2F%28%28x%2B1%29%29; add like terms
:
%2811%28x+%2B+1%29%29%2F%28%28x%2B1%29%29; factor out 11
:
(x+1)'s cancel, so ans = 11
