Which system of equations has the same soultion as the system below? 2x+2y=-4 4x+y=13

The solution is ;  x = 5  and y= -7

Step-by-step explanation:

The two inequality equations are given as;

2x + 2y = -4 {i}

4x  +  y = 13 {ii}

Making the x terms equal by multiply equation {i} by 4 and {ii} by 2 to get

{2x + 2y = -4 } 4

{4x  +  y = 13 } 2

8x + 8y = -16

8x  + 2y =  26

        6y = -42

         y= -42/6

        y= - 7

Use y= -7 in the equation  4x + y = 13

4 x - 7 = 13

4x = 13 + 7

4x = 20

x= 20/4

x= 5

The solution is ;  x = 5  and y= -7
