Answer:

Step-by-step explanation:

-2x - 5y =-2

⇒-6x - 15y= -6....(1)                [multiplying 3]

3x+6y=-3

⇒6x+ 12y = -6 (2)           [multiplying 2]

(1) + (2)

-6x-15y +6x+12y = -6 -6

⇒-3y=-12

⇒ y = 4

y=4 I guess

Answer:

4

Step-by-step explanation:

-2X - 5Y= -2 ------------(1)

3X+6Y = -3--------------(2)

TO ELIMINATE Y MULTIPLY EQUATION (1) BY 3 AND EQUATION (2) BY 2

-2X-5Y= -2-----------×3

3X+6Y= -3------------×2

-6X-15Y = -6

6X+ 12Y = -6

adding the two new equations

0 -3Y = -12

-3Y = -12

Y = -12/-3

Y = 4
