Mathematics
1 answer:
SSSSS [86.1K]3 years ago
8 0

Answer:

{x,y} = {3,-2}

Step-by-step explanation:

// Solve equation [1] for the variable  y

 [1]    y = 2x - 8

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

  [2]    3x - 2•(2x-8) = 13

  [2]    -x = -3

// Solve equation [2] for the variable  x

  [2]    x = 3

// By now we know this much :

   x = 3

   y = 2x-8

// Use the  x  value to solve for  y

   y = 2(3)-8 = -2

Solution :

{x,y} = {3,-2}
