Respuesta:

$$\begin{lgathered}-\frac{2}{3}-\frac{4}{7}x=-2\\\\-\frac{2}{3}-\frac{4}{7}x+\frac{2}{3}=-2+\frac{2}{3}\\\\-\frac{4}{7}x=-\frac{4}{3}\\\\7\left(-\frac{4}{7}x\right)=7\left(-\frac{4}{3}\right)\\\\simplificar:\\\\-4x=-\frac{28}{3}\\\\\mathrm{Dividir\:ambos\:lados\:entre\:}-4\\\\\frac{-4x}{-4}=\frac{-\frac{28}{3}}{-4}\\\\simplificar:\\\\x=\frac{7}{3}\end{lgathered}$$
