y=-3 and then x=-1 =-3:-1
Answer:.
Step-by-step explanation:.
Answer:
The coordinates are x = -1 and y = -2.
Step-by-step explanation:
Given:
Equations are 2x-4y=6 and 3x+y=-5.
Now, to find the coordinates.
...........(1)
...........(2)
So, first we solve the equation 1 to get the value of
.

Subtracting both sides by
we get:

Dividing both sides by 2 we get:

Now, we put the value of
in equation 2 to get
.




On solving the whole equation we get :

And, now putting the value of
in equation (1) we get
:





on solving we get:

Therefore, the coordinates are x=-1 and y=-2.
