\left\{ \begin{array} { l } { 6 + m = n + 10 } \\ { \frac { 1 } { 4 } m ^ { 2 } - m - 3 = \frac { 3 } { 10 } - 3 } \end{array} \right.
Solve for m, n
m=-\frac{\sqrt{130}}{5}+2\approx -0.28035085\text{, }n=-\frac{\sqrt{130}}{5}-2\approx -4.28035085
m=\frac{\sqrt{130}}{5}+2\approx 4.28035085\text{, }n=\frac{\sqrt{130}}{5}-2\approx 0.28035085
