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
