Answer:

x=

x=5.92 or -5.92

Step-by-step explanation:

Given the equation:


(x)/(3)*(x)/(7)=(5)/(3)

Combine the fractions on the left-hand side by multiplying:


\implies(x^2)/(21)=(5)/(3)

Next, multiply both sides by 21:


\begin{gathered} (x^2)/(21)*21=(5)/(3)*21 \\ \implies x^2=35 \end{gathered}

Finally, find the square root of both sides:


\begin{gathered} √(x^2)=\pm√(35) \\ x=\pm\sqrt[]{35} \\ x=\sqrt[]{35}\text{ or x=-}\sqrt[]{35} \\ x\approx5.92\text{ or }-5.92 \end{gathered}
