Answer:
2k - 13
Step-by-step explanation:
1. Because this is an expression, we can only simplify it.
2. (Solving)
Step 1: Apply distributive property.
- [tex]-3(2 + 4k) + 7(2k-1)[/tex]
- [tex](-3)(2) + (-3)(4k) + (7)(2k) + (7)(-1)[/tex]
- [tex]-6 - 12k + 14k - 7[/tex]
Step 2: Combine like terms.
- [tex](-12k+14k) + (-6 - 7)[/tex]
- [tex]2k - 13[/tex]
Therefore, the answer is 2k - 13!
