What is the solution to the system of equations that contains −3x + y = 3 and 2x − y = −1? a) no solution b) (−1, 3) c) infinite number of solutions d) (−2, −3)

The  Answer to this problem is (D)

6

Explanation:

You can multiply the numerator by the numerator and the denominator by the denominator.

The numerator of 12 is 12 and denominator of 12 is 1.

Simplify this fraction and you get 6 over 1 or just 6.

You can also use common sense (not really).

You probably know that 1/2 is one half. To find half of something, you would normally divide by 2. 12 divided by 2 is 6.
