The number is color(red)(12)

Explanation:

Let the number be represented by the variable color(blue)n

We are told
color(white)("XXX")color(blue)n/6+5=7

Subtracting 5 from both sides gives
color(white)("XXX")color(blue)(n)/6=2

Then multiplying both sides by 6
color(white)("XXX")color(blue)n=12

I got 12

Explanation:

I interpreted the question as:

x/6+5=7

where x is our unknown number.

Solving for x:

x/6=7-5

x=6*2=12

210

Explanation:

If you meant a number dividing by 6 then 5 then the answer is 210. If you don't mean that, I'm very sorry.
Let "the sum of a number" be x.
x divided by 6 then divided by 5 = 7
Now, let's work backwards.
Let y be the unknown.
x divided by 6 is y. y divided by 5 is 7
To find y, we take 7*5=35.
Then, to find x, we take y*6.
y is 35.
35*6=210
