Answer: y=1

Explanation:

Add the two equations together:

(2x - y) + (2x + y) = (-3) + (-1)

This simplifies to:

4x = -4

Now, divide both sides of the equation by 4 to solve for x:

4x/4 = -4/4

x = -1

Now that we know the value of x, we can substitute it back into either of the original equations to find the value of y.

2(-1) - y = -3

Simplifying this equation gives:

-2 - y = -3

Next, isolate y by adding 2 to both sides of the equation:

-2 + 2 - y = -3 + 2

This simplifies to:

-y = -1

Finally, multiply both sides of the equation by -1 to solve for y:

-y * -1 = -1 * -1

y = 1
