7x + 1y - 5 - 11x + 35 + 2y - 7 - 4x + 3y - 37 - 5x - 2y + 14 - 4x + 4y - 21 - 4x + 3y + 23 + 4x + 3y + 22

-5, 35, -7, -37, 14, -21, 23 and 22 are like terms. When added together they equal 23.

7x, -11x -4x, -5x -4x, -4x and 4x are like terms. When added together they equal -17x

1y, 2y, 3y, -2y, 4y, 3y and 3y are like terms. When added together they equal 14y.

The end result is 23 - 17x + 14y

Hope this helps
