Question

Solve for Q: V= Q/x - Q/y

A) Q= x+y/Vxy
B) Q= Vxy/y-x

Answer 1

first step towards the solution:
V= Q/x - Q/y=Q(1/x - 1/y)

Answer 2

\[V=\frac{Q}{x}-\frac{Q}{y}\] clear fractions by multiplying by \(xy\)
\[xyV=yQ-xQ\]factor our a \(Q\)
\[xyV=(y-x)Q\] last step is to divide to get \(Q\) by itself

Answer 3
