Y = - x + 4 y = 2x - 8

{y,x} = {0,4}

Step-by-step explanation:

// Solve equation [2] for the variable  y  

 [2]    y = 2x - 8

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

  [1]    (2x-8) + x = 4

  [1]    3x = 12

// Solve equation [1] for the variable  x  

  [1]    3x = 12  

  [1]    x = 4  

// By now we know this much :

   y = 2x-8

   x = 4

// Use the  x  value to solve for  y  

   y = 2(4)-8 = 0

answer: i believe its b. if you sound out the sentences that sounds wrong.
