2a + 3b - a
(4x + 3y) - (2x -5y)
(Hint: Remember to distribute the negative to the second set of parentheses.)
-3(2x - 1) - 5
7xy - 2xz + 4xz - 12xyz + 2zx
(Hint: The "xz" terms and the "zx" terms are alike so they can be combined.)
-3(2x - 5) - 4(x + 7)

These are the correct answers:
$$a+3b$$$$2x+8y$$$$-2-6x$$$$7xy+4xz+-12xyz $$ or $$x(y(7-12z)+4z)$$$$-13-10x$$Hope i helped, lemme know by giving me a medal
