Solve the folowing system of equations
\begin{cases} \text{ if } {x}^{3}(1-x)+{y}^{3}(1-y) =12xy+18\\ \text{ if } |3x-2y+10|+|2x-3y|=10 \end{cases}
thth776, I checked the plot for both equations.
Study these two links:
abs(3x - 2y + 10) + abs(2x - 3y) = 10 - Wolfram|Alpha
x^3(1 - x) + y^3(1 - y) = 12xy + 18 - Wolfram|Alpha
I hope this steers you in the right direction.
