7 17/18. Put them both over 18 and add so they have the same denominator
Answer:
- 7
Step-by-step explanation:
Given
t < - 6
Then t = - 7 is less than - 6 and is a solution
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
