Final answer:
To find the sum of (x + 5), (-4x - 2), and (2x - 1), combine the like terms. The sum is 3x + 2.
Step-by-step explanation:
To find the sum of (x + 5), (-4x - 2), and (2x - 1), we need to add the like terms together. The like terms have the same variable and exponent. So, combining the x terms, we have x + 2x = 3x. Combining the constant terms, we have 5 + (-2) + (-1) = 2. Therefore, the sum of the three terms is 3x + 2.
