Answer:
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
n
3
To add
5
to the quotient would then give us the expression
n
3
+
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:
n
3
+
5
=
8
n
3
+
5
−
5
=
8
−
5
n
3
+
0
=
3
n
3
=
3
3
⋅
n
3
=
3
⋅
3
1
n
=
9
n
=
9
