The system has no solution.

Work Step by Step

From equation (I) put the value of x in the equation (II) and solve for y, $9-2y+2y=13$ $9=13$ (III) According to the equation (III) $9=13$ indicates that the system is inconsistent and has no solution. So, the solution set is the empty set. Thus, the system has no solutions.
