It's given that,
Our expression is 'k - 7'. We already have the value of k, so to solve it we need to substitute the value given in the place of k.
![k - 7 \\ = (4) - 7 \\ = 4 - 7 \\ = \large\boxed{\boxed{ \bf- 3}}](https://img.qammunity.org/2022/formulas/mathematics/high-school/4zm7frx58re6evxjcbqxqpgeszlkh62xeg.png)
- The value of the expression will be -3.
