The sum of the quotient of a number and 3 and 8 is 16."

One needs to translate from English to mathematics symbols. Sometimes, the words can be translated directly, piece by piece, from left-to-right, then the parts can be put together.

This one is one of those "left-to-right." translations:
"The sum of" involves adding two things, so we start with:
# ("the first thing") + ("the second thing") #

"is" translates to "=". So,
# color(blue)( ("the first thing") + ("the second thing") = 16 ) #.

Using "x" for everything can make the eyes sore, so here we use "N" for the unknown Number.

the first thing:
"the quotient of a number and 3". Since "quotient of" means divide the first thing mentioned (an unknown number, N) by the second thing mentioned (3).
# N -: 3 = N/3 #

We can fill-in part of the expression:
# color(blue)( ( N/3 ) + ("the second thing") = 16 ) #

the second thing:
The second thing being added is 8.

Now, finish the translation with a full equation:
# color(red)( N/3 + (8) = 16 ) #

To solve the math problem, subtract 8 from both sides of the equation, then multiply both sides of the result by 3.

You should get: # color(red)( N = 24 #.
