Answer:

the answer is 31!

Step-by-step explanation:

So if you do 12 x 3 that is 36 and 36-5 is 31

so then you see if it works

31 +5 = 36

36/3 = 12

Answer:

number: 31

Let the number be x

This number is added by 5, so: x + 5

Then we divide it total by 3, so: (x + 5)/3

And this equals to 12, (x + 5)/3 = 12

Solve for unknown number:

(x + 5)/3 = 12

x + 5 = 36

x = 36 - 5

x = 31
