Your answer is B) 12y = 4
You can find this by first rearranging the equation x + 3y = -2 to the form ‘x =‘:
x = -2 - 3y.
Then you can substitute this into the second equation, 2x - 6y = -8, and expand and solve:
2(-2 - 3y) - 6y = -8
-4 - 6y - 6y = -8
-12y = -4
Now because we know that -12y = -4, this is equivalent to 12y = 4, which is option B.
I hope this helps! Let me know if you have any questions :)
If two planes are perpendicular, they intersect. if two planes are parallel, they will never touch. hope this helps
