Question 52711
Multiply both sides by 5 and get {{{3+x-6=15}}}, which simplifies to {{{x-3=15}}}.  Adding 3 to both sides gives us {{{x=18}}}.  To check our answer, substitute 18 in for x in the original equation thusly: {{{((3+18)-6)/5=3}}}, which simplifies to {{{(21-6)/5=3}}}, which simplifies further to {{{15/5=3}}}, which equates to {{{3=3}}}.  Because 3=3 is a true statement, that means our answer of x=18 is correct.
