$\left\{ x| x=\dfrac{3}{4} \right\}$

Work Step by Step

Using the properties of equality, the given equation, $ 7x-3+2x=9x-8x ,$ is equivalent to \begin{array}{l}\require{cancel} 5x-3=x \\\\ 5x-x=3 \\\\ 4x=3 \\\\ x=\dfrac{3}{4} .\end{array} Hence, the solution is $ \left\{ x| x=\dfrac{3}{4} \right\} .$
