Brainliest Edward is solving the following system of equation using elimination:

-4x+2y=-20− 4 x + 2 y = − 20

6x-5y=306 x − 5 y = 30

Edwards work is shown below:

Step 1: 5(-4x + 2y) = 5(-20)

+ 2(12x - 5y) = 2(30)

Step 2 -20x + 10y = -100

+ 24x - 10y = 60

Step 3: 4x = -40

Step 4: x = -10

Edward claims the value of x = -10.

Is Edward correct? Explain why or why not.
