Step-by-step explanation:
2 × (3^6 × 3^-5) = 6
Answer:
The system has no solutions.
Step-by-step explanation:
Let's write it in a more traditional form

Try staring at it for a bit, and then realize what you are being asked: find two numbers whose difference is - at the same time, 7, and -7/6. That's impossible.
Same result you get by elimination. Multiply the first by 6 and either add or subtract - your choice the second. In either case you will get 0 = 35 or 0=49, which are obviously absurd
Answer:
-88/85
Step-by-step explanation:
2 14/49=112/49
7 3/85=598/85
3 35/49=182/49
------------------------
112/49-(598/85-182/49)
112/49-1976/595
-88/85
The answer is 15
Hope this helps you
