Question

Solve simultaneously x+y=24 2x – y = -6

Answer 1

Answer:

(x,y) = (6,18).

Step-by-step explanation:

Given :-  x+y=24  ---------------------(1)

 and      2x-y=-6    -------------------(2)

(1) + (2)  => 3x = 18  => x = 6

Now, put x=6 in (1), we get

=> 6+ y = 24

=> y = 18

Answer 2

Answer:

x= 6 and y= 18

Step-by-step explanation:

the given system of equation is

       x+y=24                       [1]

       2x - y = -6                   [2]  

adding equation(1) and (2) ,we get

     x + y = 24

   2x -y  = -6

   3x    = 18

    x = 18/3

    x = 6

putting x=6 in equation(1) , we get

    6 + y = 24

    y = 24 - 6

    y = 18      

hence the solution are  x = 6 and y = 18
