Answer:
hope this will help you !
Step-by-step explanation:
By elimination method
2x - y = 3..........equation1
x + 2y = -1 .........equation 2
multiplying equation2 by (-2)
2x - y = 3
-2x - 2y = 2
-3y = 5
y = - 5/3
now putting value of y in equation 1
2x - (-5/3) = 3
2x + 5/3 =3
2x = 3- 5/3
2x = 4/3
x = 4/3 × 1/2
x = 2/3
therefore, x = 2/3
y = -5/3
