Question

4/x + 2/y = 11 ,3/x-5/y=-2​

Answer 1

Answer:

// Solve equation [2] for the variable x

[2] 3x = 5y - 8

[2] x = 5y/3 - 8/3

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

[1] 4•(5y/3-8/3) + 2y = 11

[1] 26y/3 = 65/3

[1] 26y = 65

// Solve equation [1] for the variable y

[1] 26y = 65

[1] y = 5/2

// By now we know this much :

x = 5y/3-8/3

y = 5/2

// Use the y value to solve for x

x = (5/3)(5/2)-8/3 = 3/2

Solution :

{x,y} = {3/2,5/2}
