hey man , i don't have time to solve but will guide you through the process
firstly y = 2x-1 / x+3
so our equation is 2y - 3/y = 5
It can be simplified as, 2y^2 - 3 = 5y
2y^2 -5y - 3 = 0 ; is your quadratic equation. Now find the y values using quad equation ; you should y = -1/2 and 3
Now y = 2x-1 / x+3; substitute 2x-1 / x+3 = -1/2 and 2x-1 / x+3 = 3
Get x values
