What is 2x+y=4 and 2x+y=-1

{x,y} = {5,6}

Step-by-step explanation:

// Solve equation [1] for the variable  x

 [1]    x = y - 1

// Plug this in for variable  x  in equation [2]

  [2]    2•(y -1) - y = 4

  [2]    y = 6

// Solve equation [2] for the variable  y

  [2]    y = 6

// By now we know this much :

   x = y-1

   y = 6

// Use the  y  value to solve for  x

   x = (6)-1 = 5
