Simplify the first equation, and then use substitution to solve the system.

6xy is the common denominator, which you should multiply both sides:

Simpler second equation is also x=y-1, substitute into the first now simplified equation.

, a quadratic equation in the variable, y, on which you can use the general solution for a quadratic equation. Many symbols to write, and doing this is much more fast and comfortable on paper than by typing text onto this webpage.
