Which expression is equivalent to 3xy − 2xz + yz + 2xy − 4xz − 5yz?

Answer 1

Adding like terms, we have:

(3xy + 2xy) + (-2xz - 4xz) + (yz - 5yz)

Simplifying each set of parentheses, we have:

5xy - 6xz - 4yz

Thus, the expression 5xy - 6xz - 4yz is equivalent to 3xy - 2xz + yz + 2xy - 4xz - 5yz.
