Solve the system

{3x + 2y = 6

{3x + 3 = y

A: (0, 3)

B: (1, 6)

C: (3, 3)

D: (-1, - 6)

The answer is A. You can get that in by plugging in and checking or by substitution. In order to use substitution here, you would plug in 3x + 3 into y in the first equation. You would then distribute the 2 and solve for x, which would give you 0. Then you could plug that into either equation to find that y = 3.
