Solve the system of equations
2x+5y=-4
-x-3y=1

y = 2  x = -7

Step-by-step explanation:

2x+5y=-4            2x + 5y = -4         Add both equations

(-x-3y=1)2           -2x - 6y =  2

                                 -y = -2

                                  y = 2

Plug in 2 for y in the equations

-x - 3(2) = 1

-x -6 = 1

-x = 7

x = -7
