BOI THE CORRECT ASNWESRS ARE 
When  (1, 2) is substituted into the second equation, the equation is true.When  (1, 2) is substituted into the first equation, the equation is true.

The ordered pair  (1, 2) is a solution to the system of linear equations.      

  By validating the statements given, (2), (4) and (5) are the correct statements.

 Given system of equations in the question is,

  • y = -2x + 4 ------(1)
  • 7x - 2y = 3 ------(2)

We will find correct statements by substituting the ordered pair (1, 2) in each equation.

By substituting (1, 2) in equation (1),

2 = -2(1) + 4

2 = 2

True.

By substituting (1, 2) in equation (2),

7(1) - 2(2) = 3

7 - 4 = 3

3 = 3

True.

  Therefore, ordered pair (1, 2) is the solution of the given system of equations.

   Hence, (1), (3) and (6) are the correct statements.
