This is calculated using:
Where:
So, by comparison:
So, we have:
B is going to be your answer
Switch the equation around and it gives you D+B/A=C. Then subtract D from both sides, which gives you B/A=C-D. Then you multiply by A which gives you B= CA - DA
Answer:
the answer is the quotient of 2+9 and 3
