Simplify (3x − 5) − (5x + 1).

3x - 5 - 5x - 1 = -2x - 6

To simplify the expression (3x - 5) - (5x + 1), we need to distribute the negative sign to the terms inside the second parentheses.

(3x - 5) - (5x + 1)
= 3x - 5 - 5x - 1

Next, we can group the like terms together.

(3x - 5 - 5x) - 1
= (3x - 5x) - 5 - 1
= -2x - 6

Therefore, the simplified expression is -2x - 6.
