Answer
$\color{blue}{\dfrac{5x}{y}}$
Work Step by Step
Factor the binomials, then cancel common factors to obtain:
$\require{cancel}
=\dfrac{x(x+1)}{5} \cdot \dfrac{5(5)}{y(x+1)}
\\=\dfrac{x\cancel{(x+1)}}{\cancel{5}} \cdot \dfrac{5\cancel{(5)}}{y\cancel{(x+1)}}
\\=\dfrac{x}{1} \cdot \dfrac{5}{y}
\\=\color{blue}{\dfrac{5x}{y}}$
