Answer:
X = 0, Y= -2
Step-by-step explanation:
Compare the x and y coordinate values
3x + 2y =-4_______(1)
2x - y = 2 ________(2)
Multiply the (2) with 2
4x - 2y = 4
and add the new equation to (1)
3x + 2y =-4
4x - 2y = 4
____________
7x = 0
X = 0
Substitute x value into (1)
3 *0 + 2y = -4
0 + 2y =-4
2y =-4
Y= -2
