1. The problem is to find the other solution of an equation given that one solution is $(3,3)$ and it is incorrect. 2. Since the user did not specify the equation, let's assume it is a quadratic equation where $(3,3)$ is a point on the curve but not a root. 3. Typically, for quadratic equations, if one root is known, the other can be found using the sum and product of roots formulas. 4. The sum of roots $\alpha + \beta = -\frac{b}{a}$ and the product of roots $\alpha \beta = \frac{c}{a}$ for equation $ax^2 + bx + c = 0$. 5. Without the exact equation, we cannot find the exact other root, but if $(3,3)$ is a point, not a root, we need the equation to proceed. 6. Please provide the equation or more context to find the other solution.
