Answer:

{x,y}={14,8}

Step-by-step explanation:

Solve equation [2] for the variable  x     [2]    x = y + 6

Plug this in for variable  x  in equation [1]   [1]    (y +6) + y = 22

  [1]    2y = 16

Solve equation [1] for the variable  y     [1]    2y = 16 

[1]    y = 8 

By now we know this much :     x = y+6,  y = 8

Use the  y  value to solve for  x.  

 x = (8)+6 = 14
