Equidistant os the awnser
Answer:
-2X/3+3
Step-by-step explanation:
Answer:
Option A is correct.
Step-by-step explanation:
We have to eliminate x from the given system of equations by solving
-6x -4y=2
-4x-7y=2
We can do this by subtracting 3 times the second equation from 2 times the first equation we get
-12x -8y = 2
12x +21y =- 2
Sign of second equation changed because it is getting subtracted
Since, we got same quantity of x with opposite signs
Hence, it will get cancelled and so eliminated.
Therefore, Option A is correct.
