Start by multiplying both sides of the equality by x

$\begin{gathered} x\cdot(3)/(x)=(9)/(10)\cdot x \\ 3=(9x)/(10) \end{gathered}$

Multiply boths sides by 10

$\begin{gathered} 3\cdot10=(9x)/(10)\cdot10 \\ 30=9x \end{gathered}$

divide both sides by 9

$\begin{gathered} (30)/(9)=(9x)/(9) \\ (30)/(9)=x \end{gathered}$

simplify the expression

$\begin{gathered} x=(30)/(9) \\ x=(10)/(3) \end{gathered}$
