Упростить. 16x+x-3x, 18xy+28xy-4,5a-3ab+8a,73c+29c+27c,5x+6x+7y+8y,57a+42b-53c

16x + x - 3x = 15x - 3x = 12x.

5a - 3ab + 8a = 13a - 3ab = a * (13 - 3b).

5x + 6x + 7y + 8y = 11x + 15y.

18xy +28xy - 4 = 46xy - 4 = 2 * (23xy - 2).

73c + 29c + 27c = 100c + 29c = 129c.

37a + 42b - 53c = 37a + 42b - 53c.
