To simplify the expression \((7x - 2) - (3x + 5)\), you can follow these steps:
1. Distribute the negative sign across the second parenthesis:
\[
(7x - 2) - (3x + 5) = 7x - 2 - 3x - 5
\]
2. Combine like terms:
- Combining the \(x\) terms: \(7x - 3x = 4x\)
- Combining the constant terms: \(-2 - 5 = -7\)
Therefore, the simplified expression is:
\[
4x - 7
\]
