How can I solve the system of equations 2xy = 7 and 5xy = 9?

To solve the system of equations 2xy = 7 and 5xy = 9, we can start by expressing each equation in terms of xy.

From the first equation:

2xy = 7 can be rearranged to find the value of xy:

  • xy = 7/2

From the second equation:

5xy = 9, we can also express xy:

  • xy = 9/5

Now we have two expressions for xy:

  • xy = 7/2
  • xy = 9/5

Since both expressions represent the same value of xy, we can set them equal to each other:

7/2 = 9/5

To solve this equation, we can cross-multiply:

  • 7  = 9 
  • 35 = 18

This indicates that there is no solution, as the equation is contradictory.

Thus, there is no solution to this system of equations as they are inconsistent.
