Answer:
n=9
Step-by-step explanation:
First, let's give a name to the number we are looking for and call it n.
So we can then write "A number is divided by 3" as n3
To add 5 to the quotient would then give us the expression n3+5
If this results in 8 we can finally write the equation we are trying to solve and solve the equation for n while keeping the equation balanced:
n3+5=8
n3+5−5=8−5
n3+0=3
n3=3
3⋅n3=3⋅3
1n=9
n=9
