Answer

$x=-\dfrac{7}{5}$

Work Step by Step

Using the properties of equality, the solution to the given equation, $ \dfrac{2x+1}{3}-\dfrac{x-1}{4}=0 ,$ is \begin{array}{l}\require{cancel} 12\left( \dfrac{2x+1}{3}-\dfrac{x-1}{4}\right)=(0)12 \\\\ 4(2x+1)-3(x-1)=0 \\\\ 8x+4-3x+3=0 \\\\ 8x-3x=-4-3 \\\\ 5x=-7 \\\\ x=-\dfrac{7}{5} .\end{array}
