Question

(8x+6) (10x+9y) 73° 110°

Answer 1

Answer:{x,y}={-1,-4}

Step-by-step explanation:

 [2]    8x = 4y + 8

 [2]    x = y/2 + 1

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

  [1]    10•(y /2+1) - 9y = 26

  [1]     - 4y = 16

// Solve equation [1] for the variable  y

  [1]    4y = - 16

  [1]    y = - 4

// By now we know this much :

   x = y/2+1

   y = -4

// Use the  y  value to solve for  x

   x = (/2)(-4)+1 = -1
