Answer:

28

Step-by-step explanation:

Let the number be x.

When 12 is subtracted from three times a certain number...

3x -12

and the result is divided by 4...

(3x -12)÷4

the answer is 18.

(3x -12) ÷4= 18

Let's work backwards to find the number.

3x-12= 18 ×4 (×4 throughout)

3x -12= 72

3x= 72 +12 (+12 on both sides)

3x= 84

x= 84 ÷3

x= 28

Thus, the number is 28.
