Answer:


x=(42)/(13)

Explanation:

Given equation:


(6)/((x^2-3x))=(12)/(x)+(1)/((x-3))

Factor the denominator on the left side:


\implies (6)/(x(x-3))=(12)/(x)+(1)/((x-3))

Combine the fractions on the right side by multiplying by the LCM:


\begin{aligned}\implies (6)/(x(x-3)) & =(12)/(x) \cdot ((x-3))/((x-3))+(1)/((x-3)) \cdot (x)/(x)\\\\& =(12(x-3))/(x(x-3))+(x)/(x(x-3))\\\\& =(12(x-3)+x)/(x(x-3)) \end{aligned}

As the denominators are now the same on both sides:


\begin{aligned}\implies (6)/(x(x-3)) & =(12(x-3)+x)/(x(x-3))\\\\ \implies 6 & = 12(x-3)+x\end{aligned}

Simplify and solve for x:


\begin{aligned}\implies 6 & = 12(x-3)+x\\\\6 & =12x-36+x\\\\6 & =13x-36\\\\13x & =42\\\\\implies x & =(42)/(13)\end{aligned}
