Question 1121667

{{{2/(x+3) -  1/(x+1) < 0}}}....common denominator first


{{{2(x+1)/((x+3)(x+1)) -  1(x+3)/((x+1)(x+3)) < 0}}}


{{{(2(x+1) -  1(x+3))/((x+1)(x+3)) < 0}}}....both side multiply by {{{(x+1)(x+3)}}}


{{{(((x+1)(x+3))(2(x+1) -  1(x+3)))/((x+1)(x+3)) < 0((x+1)(x+3))}}}


{{{(cross(((x+1)(x+3)))(2(x+1) -  1(x+3)))/cross(((x+1)(x+3))) < 0}}}


{{{2(x+1) -  1(x+3)< 0}}}


{{{2x+2 -  (x+3)< 0}}}


{{{2x+2 -  x-3< 0}}}


{{{x-1< 0}}}


{{{x-1+1< 0+1}}}


{{{x< 1}}}
