Answer:
No solutions.
Step-by-step explanation:
We need to use PEMDAS to solve this problem, and as the first letter in PEMDAS stands for (parentheses) we should subtract 7 from 15 to get 8.
Secondly, we would multiply 2 by 8 to get 16.
Finally, we subtract 9 from 16 to get 7.
64 ≠ 7, so the answer would be no solutions.
