What is the result of adding these two equations -2x+7y=-5, -2x-4y=6

-4x+3y=1

Step-by-step explanation:

First put the equations above one another

-2x+7y=-5

-2x-4y= 6

Just add the corresponding number from the top from the one right below it

-2x plus -2x is 4x

7y plus -4y is 3y

-5 plus 6

Then bring down the equal sign

And you get

-4x+3y=1
