Answer 2

SOLUTION:-

the correct answer is 5

Step-by-step explanation:

hit and trial method states that use every possible value from lowest value to highest or vice versa

therefore, we will first use 0 in the given equation but if we put it we will get 3×0=0 and 0 is not equal to 15.

now, we will use 1 in the given equation but if we put it we will get 3×1=3 and 1 is not equal to 15.

now, we will use 2 in the given equation but if we put it we will get 3×2=6 and 6 is not equal to 15.

now, we will use 3 in the given equation but if we put it we will get 3×3=9 and 9 is not equal to 15.

now, we will use 4 in the given equation but if we put it we will get 3×4=12 and 12 is not equal to 15.

now, we will use 5 in the given equation but if we put it we will get 3×5=15 and 15 is equal to 15.

therefore, we will get our answer that is 5.
