It looks like your question is imcomplete, or your internet connection timed out before you could finish typing/attaching a photo.
Anyway, could you repost a complete question or put in your input to what you think is the first step of this problem?
Thanks!

2. x³ + 8x + 13
3. 8x + 5
4. 3x² + 2x +4
5. 2x³ + 5x
6. 2x³ - 2x - 6
I think you meant...
3^(3x-7)=81^(12-3x) (note that 81=3^4) so
3^(3x-7)=3^4^(12-3x)
3^(3x-7)=3^(48-12x) taking log or natural log of both sides show that
3x-7=48-12x
15x=55
x=11/3
