Step-by-step explanation:
Hi,
x+2y = -1 -------(1)
2x-3y=12 ---------(2)
From (1) , we get
x + 2y = -1
x = -1 - 2y -------(3)
putting the value of x in (2) , we get
2x - 3y = 12
2 ( -1 - 2y ) - 3y = 12
-2 - 4y - 3y = 12
-7y = 12 + 2
y = 14/-7
y = -2
Put the value of y in (3) , we get
x = -1 - 2y
x = -1 - 2*-2
x = -1 + 4 = 3.
Hence,
( X, Y ) = ( 3 , - 2 )
Hope it will help you :)
