Question

Solve the system of equations. X-3y=-6 2 = y + 3 X = y =

Answer 1

 x - 3y = -6

2x - y = 3

-3y + x = -6        y + 2x = 3  

 

Solve by Substitution :

// Solve equation [1] for the variable  x

 [1]    x = 3y - 6

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

  [2]    2•(3y-6) - y = 3

  [2]    5y = 15

// Solve equation [2] for the variable  y

  [2]    5y = 15

  [2]    y = 3

// By now we know this much :

   x = 3y-6

   y = 3

// Use the  y  value to solve for  x

   x = 3(3)-6 = 3

Solution :

{x,y} = {3,3}

-FrxziteTheLxoser- Hoped this help! :)

If you dont understand the answer is {x,y = {3,3}
