B. r <8 because you ad 3 to both sides. it cancels out on the right side.
Answer:
D
Step-by-step explanation:
Answer:
(x, y) = (7, -7)
Step-by-step explanation:
You can eliminate y by adding the two equations:
(3x -y) +(3x +y) = (28) +(14)
6x = 42 . . . . simplify
x = 7 . . . . . . divide by 6
You can eliminate x by subtracting the two equations:
(3x +y) -(3x -y) = (14) -(28)
2y = -14 . . . . simplify
y = -7 . . . . . . divide by 2
The solution is (x, y) = (7, -7).
It’ll be the one on the far right last one ;)
