Find my number, if the product of my number and 3 is 15 more than the sum of my number and 3.

Your number is 9.

Step-by-step explanation:

9 x 3 = 27

27 - 15 = 12

9 + 3 = 12

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
