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
