Simplify the expression.


(Simplify your answer. Use integers or decimals for any numbers in the expression.)

To simplify the expression, combine like terms. The constants and add up to . Now, for the terms, we have and . When you add these coefficients, gives you . So, the final simplified expression is indeed:

.

You nailed it! Always keep an eye out for grouping like terms; it’s like organizing your closet—makes everything easier to find!

And if simplicity is your jam, remember that combining numbers and coefficients upfront can save you time and keep from losing track of your calculations. Double-checking your signs helps, too—nobody likes a surprise negative! Keep practicing!
