8*a=32
32:8=a
4=a
4+26=b
30=b
Answer:
C. x = 12
Step-by-step explanation:
5(12) + 9 = 69 - 3(12) = 33
18 + 15 = 33
Remember the properties of logarithms. If you have ln81, you can pull out the power of two (9^2) and have 2ln9. Also, you could do ln9 + ln9 because 9*9=81 and ln9*9 = ln9 + ln9
With these properties, you can get 3lnx+2lny, which is 3u+2v according to the answer.
