( Multi-step equations)
show work please and thank you

Step-by-step explanation:

7(3+4y)-15y=73

21 plus 28y-15y=73

21 plus 13y = 73

13y=51

y=4

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✌✌✌
