Answer:
55-276x
Step-by-step explanation:
To solve this question, you will have to follow some specific principles to prevent error
So to solve this we will have to follow the BODMAS rule
9-3(45x+47x)-2+66
Deal with the bracket first
3(45x+47x)
3(92x)
276x
Then back to the question
9-276x-2+66
Collect like terms
9-2+66-276x
Add comes before substration according to bodmas
9+64-276x
55-276x
This cannot be solved further because they are different from each other
Therefore the final answer is 55-276x
