To determine if an ordered pair is a solution to a system of linear equations in two variables, a.. substitute the coordinates of the ordered pair into either equation to see if it produces a true statement. b.. substitute the coordinates of the ordered pair in both equations to see if it produces a true statement for each. c.. substitute the coordinates of the ordered pair in the first equation to see if it produces a true statement. d.. substitute the coordinates of the ordered pair in the second equation to see if it produces a true statement

                    Option: B

B. substitute the coordinates of the ordered pair in both equations to see if it produces a true statement for each.

Solution to the system of linear equations is a set of the ordered pair (x,y) such that it satisfy both the equations and make both the equations true.

We solve the system of linear equations by different methods such as substitution method (In this method we substitute the value of one variable in terms of other variable from one equation into the other to find the value of both the variables which is the solution) , elimination method (In this method by applying some operations such as multiplying a equation by some variable and then subtract or add to the other equation we find the solution set)  etc.
