Answer

$x=-\dfrac{1}{5}$

Work Step by Step

By cross-multiplication, the solution to the given equation, $ \dfrac{2x+3}{3x-2}=\dfrac{4x+1}{6x+1} ,$ is \begin{array}{l} (2x+3)(6x+1)=(3x-2)(4x+1) \\\\ 12x^2+2x+18x+3=12x^2+3x-8x-2 \\\\ (12x^2-12x^2)+(2x+18x-3x+8x)=-2-3 \\\\ 25x=-5 \\\\ x=-\dfrac{5}{25} \\\\ x=-\dfrac{1}{5} .\end{array}
