Question 85667
{{{ 5/(x + 6) + 2/(x^2 + 7x + 6) = 3/(x + 1) }}}
{{{ 5/(x + 6) + 2/((x + 1)(x + 6)) = 3/(x + 1) }}}
{{{ 5(x + 1)/(x + 6) + 2(x + 1)/((x + 1)(x + 6)) = 3(x + 1)/(x + 1) }}}
{{{ 5(x + 1)/(x + 6) + 2/(x + 6) = 3 }}}
{{{ 5(x + 1)(x + 6)/(x + 6) + 2(x + 6)/(x + 6) = 3(x + 6) }}}
{{{ 5x + 5 + 2 = 3x + 18 }}}
{{{ 2x = 11 }}}
{{{ x = 11/2 }}}
