7. 2x + 3(x – 2) – 3(x – 6) (1 point)
2x + 12
2x – 8
8x – 24
2x – 24
I do not understand how to do this.

Simplify by combining terms.
2x + 3(x – 2) – 3(x – 6)
2x + 3x  6  3x + 18
2x + 12

Can you please herlp me with this too?
A baseball bat and 8 baseballs cost $163.25. The bat costs $106.45. What is the cost c of one baseball? (1 point)
163.25 – 8c = 106.45; $33.71
8c + 106.45 = 163.25; $7.10
8c + 163.25 = 106.45; $7.10
8c – 106.45 = 163.25; $33.71
