Question

If 20 -x = 15, what is the value of 3x

Answer 1

15

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!

20-x=15

-x=15/20

x=-15/20

x=3/4

3x
