Ineed with this quick extra points and i’m marking brainlist to step by step explanation

A, B and C

Step-by-step explanation:

To determine which ordered pairs are solutions, substitute the x and y coordinates into the system of equations and if the value equals the right side then the ordered pair is a solution

A (6 , 3 )

(3 × 6) - 3 = 18 - 3 = 15 ← correct, and

(6 × 6) - (2 × 3) = 36 - 6 = 30 ← correct

Hence (6, 3 ) is a solution

B (7, 6 )

(3 × 7) - 6 = 21 - 6 = 15 ← correct, and

(6 × 7) - (2 × 6) = 42 - 12 = 30 ← correct

Hence (7, 6 ) is a solution

C (8, 9 )

(3 × 8) - 9 = 24 - 9 = 15 ← correct, and

(6 × 8) - (2 × 9) = 48 - 18 = 30 ← correct

Hence (8, 9 ) is a solution

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✌✌✌
