Answer 1

0x e 4y
3x e 3y
3xy
-2xy
ab e bc e 2ac
-3xy e 10xz

Answer 2

A) 3x + 5x - 8y + 7y - 8x +5 =
= 8x - 1y -8x + 5 =
= 0x - y + 5 =
= y - 5

B) x + y + x + y + x + y =
= 3x + 3y

C) 8xy - 3xy + 7xy - 8xy - xy =
= 5xy + 7xy - 8xy - xy =
= 12xy - 8xy - xy =
= 4xy - xy =
= 3xy

D) 3xy + 5xy =
= 8xy

E) ab + bc +ac - bc + ac =
= ab + 0bc + 2ac =
= ab + 2ac

F) xy + xy +xz - 5xy + 9xz =
= 2xy + 10xz - 5xy =
= -3xy + 10xz
