Answer 1

Solving the System of Equations

To solve the system of equations:

{2xy - x = -9 {2xy - y = -14

We can use the method of elimination. The goal is to eliminate one variable by adding or subtracting the equations. Let's proceed with the solution.

1. Subtract the second equation from the first equation: (2xy - x) - (2xy - y) = (-9) - (-14)

Simplifying the equation, we get: 2xy - x - 2xy + y = -9 + 14

2. Combine like terms: -x + y = 5

Now we have a new equation: -x + y = 5

Conclusion

The solution to the system of equations is: -x + y = 5
