To determine which expression is equivalent to \(-3x - 5\), we'll simplify each of the provided options.
-
Option: \(-1 + 3x - (2x + 6)\)
Simplifying: \[ -1 + 3x - 2x - 6 = -1 + x - 6 = x - 7 \] (Not equivalent)
-
Option: \((x - 7) + (2 - 4x)\)
Simplifying: \[ x - 7 + 2 - 4x = x - 4x - 7 + 2 = -3x - 5 \] (Equivalent)
-
Option: \(-1 + (x - 4x) + 6\)
Simplifying: \[ -1 + x - 4x + 6 = -1 - 3x + 6 = -3x + 5 \] (Not equivalent)
-
Option: \((-4x - 6) + (2 + 5x)\)
Simplifying: \[ -4x - 6 + 2 + 5x = -4x + 5x - 6 + 2 = x - 4 \] (Not equivalent)
The only expression that simplifies to \(-3x - 5\) is the second option:
\[ (x - 7) + (2 - 4x). \]
