What is the solution to the system of the equations? x = y - 3 x + 3y = 13

Solution (1, 4)

Step-by-step explanation:

x = y - 3

x + 3y = 13

Substitute x = y - 3  into x + 3y = 13

y - 3  + 3y = 13

4y - 3 = 3

4y =16

y = 4

Substitute y = 4 into x = y - 3

x = 4 - 3

x = 1

Solution (1, 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
