Question

16/xy +24/xy=4 1equation
24/x-y+16/x+y=4.5. 2equation

Answer 1

Answer:

Step-by-step explanation:

// Solve equation [2] for the variable  x

 [2]    x = y + 24

// Plug this in for variable  x  in equation [1]

  [1]    (y +24) + y = 16

  [1]    2y = -8

// Solve equation [1] for the variable  y

  [1]    2y = - 8

  [1]    y = - 4

// By now we know this much :

   x = y+24

   y = -4

// Use the  y  value to solve for  x

   x = (-4)+24 = 20

{x,y} = {20,-4}
