I don't know if it's right
B.
• x+2y=-6
• x-2y=-6
Step-by-step explanation:
Try the solution in the equations and choose the set of equations that is true.
___
A. -6+0 ≠ 0 . . . not this system
__
B. -6 +2·0 = -6 . . . true
-6 -2·0 = -6 . . . true . . . . . this system has solution (-6, 0)
C. -6 -6·0 ≠ 1 . . . not this system
D. 4(-6)+3·0 ≠ -18 . . . not this system
