Answer:

15

Step-by-step explanation:

since you are trying to find the value of X you need to take 20 and subtract it by 15       20 - 15 =  5      which means  20 - 5 = 15

we now know  x = 5

we now have to multiply 3*x

since we know x = 5 we multiply  3*5 and get 15

3*5= 15

hope this helps!
