There is no solution to this system of equations, because the two equations lead to a contradiction.
y cannot be equal to both 2/3+1 and 2/3-1 at the same time.
The first equation suggests that y is greater than or equal to 5/3, while the second equation suggests that y is less than or equal to -1/3.
Therefore, these two equations cannot be satisfied simultaneously, and the system has no solution.
