Answer:
x =3 and y =1
Step-by-step explanation:
( x+y , x-2y) = (4 , 1)
compare their corresponding elements
x+y = 4
y = 4 - x equation (i)
x-2y =1
substitute the value of x
x - 2(4 - x) =1
x - 8 + 2x =1
3x = 1 +8
x = 9/3
x = 3
Now substitute the value of x in equation (i)
y = 4 - x
y = 4 - 3
y = 1
B) A line that shows only one solution to the equation
