Answer:
11
Explanation:
Focus on the product of a number and three part first
3×X=?
next it says 18 is 15 less than the product so the product is equal to
18+15=33
now Rewrite the initial equation with the product
3×X=33
now divide by three on both sides to isolate the X , that will result in
X=11
good luck!!! I believe in you!!!
