Answer:

x,y =3,-4

Step-by-step explanation:

// Solve equation [1] for the variable  y

 [1]    y = 2x - 10

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

  [2]    3x - 2•(2x-10) = 17

  [2]    -x = -3

// Solve equation [2] for the variable  x

  [2]    x = 3

// By now we know this much :

   x = 3

   y = 2x-10

// Use the  x  value to solve for  y

   y = 2(3)-10 = -4
