Choose a method that can be used to solve this system by ELIMINATION.
2x-2y=242x−2y=24
4x+7y=-404x+7y=−40
Subtract 2x from both sides and solve the first equation for y
Multiply the first equation by -2, then add.
Add the first equation to the second equation and subtract 6x from both sides.
Subtract 7y from the second equation and add the first equation.
