$y = -\frac{2472}{245} = -10\frac{22}{245} \approx -10.089795918$
$$7x-10^{-1}=1$$
$$7x-\frac{1}{10}=1$$
$$7x=1+\frac{1}{10}$$
$$7x=\frac{11}{10}$$
$$x=\frac{\frac{11}{10}}{7}$$
$$x=\frac{11}{10\times 7}$$
$$x=\frac{11}{70}$$
$$y=\frac{11}{70}-10\times \left(\frac{11}{70}\right)^{2}-10$$
$$y=\frac{11}{70}-10\times \frac{121}{4900}-10$$
$$y=\frac{11}{70}-\frac{121}{490}-10$$
$$y=-\frac{22}{245}-10$$
$$y=-\frac{2472}{245}$$
$$x=\frac{11}{70}$$ $$y=-\frac{2472}{245}$$
