Question 557481
Let n be the number you are looking for.
The quotient of a number (that's n) and 3 is expressed by:
{{{n/3}}} but you need four more than that so you just add 4 to get:
{{{n/3 + 4 = 11}}} Multiply through by 3 to clear the fraction.
{{{3*n/3 + 3*4 = 3*11}}} Simplify.
{{{n+12 = 33}}} Subtract 12 from both sides.
{{{n = 21}}}
