There are no secondary variables. The first two equations in which we find the primary minor become primary equations. We solve the system formed by the primary equations. $\begin{cases} 2\cdot x + 3\cdot y = 5\\ -3 \cdot x + 2\cdot y = -1\\ \end{cases}$ We multiply the first equation by 3 and the second one by 2.
