Answer:
2nd option
Step-by-step explanation:
Graph both equations and find the point where they both intersect. In this case, it's (4,2).
B - 3A = 2
3B - 6A = 12
(2)B - (6)A =4
3B - 6A = 12
Subtract
-B = -8
B = 8
Plugin 8 for B
8 - 3A = 2
8 = 3A + 2
6 = 3A
2 = A
(Double checking)
3(8) - 6A = 12
-6A = 12-24 = -12
- 6A = -12
Divide by -6
A= 2
It works
A = 2. B = 8. Hope this helps
So here just plug values into the quadratic formula x= -b+- sqr b^2-4ac / 2a
