Answer:
1) Solution (2,-3)
2) Solution (-1,
)
3) Solution (
)
Step-by-step explanation:
We need to solve equations using elimination
1) 
Let:

Adding both equations:

We get value of x = 2
Now, put value of x into equation 1 to find value of y

So, we get y = -3
Solution (2,-3)
2) 
Let:

Adding both equations

We get: y= -3/2
Now find value of x by putting value of y in eq(1)

We get x = -1
Solution (-1,
)
3) 
let:

Add both equations:

We get x = -1/2
Now, put value of x in equation 2

We get y = -5/2
Solution (
