Question 51404
First subtract 3 from both sides:  {{{3-6b-3<=-3-3}}}, which simplifies to {{{-6b<=-6}}}.  We now divide both sides by -6:  {{{-6b/-6 <= -6/-6}}}, which simplifies to {{{b <= 1}}}.  However, because we are dividing by a negative number in an inequality, we must reverse the inequality to produce {{{b>= 1}}}.
