x = -1
y = -1
Explanation:
2x - y = - 1 -------------------(1)
3x + 2y = - 5 --------------(2)
Solve equation (1) for y
-y = - 1 - 2x
y = 1 + 2x
Put the value y = 1 + 2x in the equation (2)
3x + 2(1 + 2x) = - 5
3x +2 + 4x = - 5
7x = - 5 - 2
x = -1
put the value x = -1 in equation (1)
3(-1) +2y = -5
-3 + 2y = -5
2y = -5 +3
