The perimeter of a rectangle is 120 m and the length is 50 m long than the width period find the dimensions of the rectangle. Let X equal the link and Y equals the width period the corresponding model system is 2X plus 2Y equals 120 and X minus Y equals 50. Solve the system graphically

Anyone know? is appreciated! will mark brainliest if correct!
