simplify the expression below.$(6x + 7xy - 8y) + (-x - 8xy + 2y)$

Explanation:

Step1: Remove parentheses

$6x + 7xy - 8y - x - 8xy + 2y$

Step2: Combine like terms for $x$

$6x - x = 5x$

Step3: Combine like terms for $xy$

$7xy - 8xy = -xy$

Step4: Combine like terms for $y$

$-8y + 2y = -6y$

Step5: Combine all results

$5x - xy - 6y$

Answer:
