ANSWER
[tex]m=\frac{W}{g}[/tex]EXPLANATION
We want to solve the given equation for m:
[tex]mg=W[/tex]This implies that we want to make m the subject of the formula.
To do this, we have to divide both sides of the equation by g and simplify:
[tex]\begin{gathered} \frac{mg}{g}=\frac{W}{g} \\ m=\frac{W}{g} \end{gathered}[/tex]That is the solution for m.
