Step-by-Step Solution
-
Distribute the negative sign: Remember that subtracting an expression is the same as adding its opposite. So, we change the minus sign in front of the second parenthesis to a plus sign and change the signs of each term inside the parenthesis.
(6x - 2y - 5) + (5 - 9y + 8x)
-
Combine like terms: Group together terms with the same variable and constant terms.
(6x + 8x) + (-2y - 9y) + (-5 + 5)
-
Simplify: Perform the addition or subtraction within each group.
(14x) + (-11y) + (0)
-
Final Expression: The simplified expression is:
14x - 11y
Conclusion
The simplified form of the expression (6x - 2y - 5) - (-5 + 9y - 8x) is 14x - 11y. By distributing the negative sign and combining like terms, we have successfully simplified the original expression.
