Pls solve the following question above ASAP.

A

Why is A the correct answer? In order to solve this problem, you must plug in the values into the equations and solve. After solving, you just see if your answer matches the number it is said to be equal to. This is how I solved:
1.) 2(2)+2(-1)+5(1)= 7 This is correct
2.) 6(2)+8(-1)+5(1)= 9 This is correct
3.) 2(2)+3(-1)+5(1)= 6 This is also right

Option A is your answer
