Answer 2

Answer:

2x + y =-4 -------------(1)

-5x+3y = -1 ------------(2)

from (1)

2x +y = -4

y = -4 -2x --------------(3)

putting the value of y in equation (2)

-5x +3y = -1

-5x +3*(-4 -2x) = -1

-5x -12 -6x = -1

-11x = -1+12

-11x = 11

x = -1

from equation (3)

y = -4 -2x

= -4 -2(-1)

= -4+2

= -2

hence, x = -1, y= -2
