Answer:
y = 3
x = -4
Step-by-step explanation:
Hopefully the first equation is x + 3y = 5
x = 5 - 3y
Plug in:
-2(5 - 3y) + 2y = 14
-10 + 6y + 2y = 14
8y = 24
y = 3
x = -4
We can employ some logic to reduce the answers we need to test. We know that the slope perpendicular to line l has to have a negative reciprocal slope, so a slope of
. We see that in A and C, as x increases so does y. That means the slope of these equations are positive, which we don't want. Now for some algebra:

We se that D has the correct slope so that must be the answer.
Ummm girl I’m sorry I do not know.
