B. 7/12
C. -3/2
D. -2/9

Given: x + y = 6. if xe (-15, -6, -1), then which of the following sets of ordered pairs are solutions? © {(-15, -21), (-6, -12), (-1, -7)} [(-15, 21), (-6, , 7)} {(-15, 21), (-6, 12), (-1, -7)}

If you answer right ill give brainliest, : )

2y= 3 2 x−2 y = − 1 3 x + 1 y=− 3 1 x+1
