Question

Help, please?
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

Answer 1

Remember, the system is only proven to be true if the coordinates effectively solve ALL of the equations...otherwise it is a flawed system.

Answer 2

So, it's B?

Answer 3

yup, you got it!

Answer 4

Thank you!
