Ответ:
x= -2, y=3
Step-by-step explanation:
2x+y=-1 (Eq-1)
-3x+2y=12 (Eq-2)
Multiply Eq-1 by 2:
2×(1): 4x+2y= -2
4x+2y= -2 (Eq-3)
Subtract Eq-3 and Eq-2:
(4x+2y)-(-3x+2y)= -2-12
4x+2y+3x-2y= -14
4x+3x+2y-2y= -14
7x= -14
x= -14÷7
x= -2
Now put x= -2 in Eq-1:
2(-2)+y=-1
-4+y= -1
y= -1+4
y= 3
Hope this helps:) Have nice day. Mark as brainliest pls.
