Answer:

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

No it isn't. 5x is 5*x. not plus. so x would be 19 since 5*19=95
