Answer:

x=-3

Step-by-step explanation:

<u>Given equation</u>:

\dfrac{2x}{x+1}+\dfrac{3(x+1)}{x}=5

Make the <u>denominators</u> the same:

\implies \dfrac{2x}{x+1} \cdot\dfrac{x}{x}+\dfrac{3(x+1)}{x} \cdot \dfrac{x+1}{x+1}=5

\implies \dfrac{2x^2}{x(x+1)}+\dfrac{3(x+1)^2}{x(x+1)} =5

<u>Combine</u> the fractions:

\implies \dfrac{2x^2+3(x+1)^2}{x(x+1)} =5

<u>Multiply</u> both sides by x(x+1):

\implies 2x^2+3(x+1)^2 =5x(x+1)

<u>Expand</u> the brackets:

\implies 2x^2+3(x^2+2x+1) =5x^2+5x

\implies 2x^2+3x^2+6x+3 =5x^2+5x

<u>Combine</u> like terms:

\implies 5x^2+6x+3=5x^2+5x

<u>Subtract</u> 5x² from both sides:

\implies 6x+3=5x

<u>Subtract</u> 5x from both sides:

\implies x+3=0

<u>Subtract</u> 3 from both sides:

\implies x=-3
