Answer:
x=1
y=-1
Explanation:
Find value of x and y
(2x+y , 2) = (1, x-y)
We can set the two values equal.
2x+y = 1
x-y =2
We now have two equations and two unknowns,
Using elimination and adding the equations together:
2x+y = 1
x-y =2
----------------
3x = 3
x =1
Now we can find the value for y
x-y =2
1-y =2
y =-1
