7 x and 7 x y
If we add 7 x y + 5 y z - 3 z x , 4 y z + 9 z x - 4 y and -3 x z + 5 x - 2 x y then the answer is
5 x y + 9 y z + 3 z x + 5 x - 4 y
5 x y - 9 y z + 3 z x - 5 x - 4 y
5 x y + 10 y z + 3 z x + 15 x - 4 y
5 x y + 10 y z + 3 z x + 5 x - 6 y
If we subtract 4 a - 7 a b + 3 b + 12 from 12 a - 9 a b + 5 b - 3 the the answer is
8 a + 2 a b + 2 b + 15
8 a + 2 a b + 2 b - 15
8 a - 2 a b + 2 b - 15
8 a - 2 a b - 2 b - 15
