Пошаговое объяснение:
(2х-3у)+(5х+2у) = 2x - 3y + 5x + 2y = 7x - y
-(р-3q)+(4q-2p) = -p + 3q + 4q - 2p = -3p + 7q
(-x+5y)-(-x-3y) = -x + 5y + x + 3y = 8y
(-3z+y)+(-16z-5y) = -3z + y - 16z - 5y = -19z - 4y
-(-3x-5c)-(3c+8x) = 3x + 5c - 3c - 8x = -5x + 2c
(-y-x)-(-y-x) = -y - x + y + x = 0
(2m-n)+(n+4m) = 2m - n + n + 4m = 6m
(p-2q)-(4q+p) = p - 2q - 4q - p = -6q
-(c+d)+(-c-3d) = -c - d - c - 3d = -2c - 4d
