Can some one please explain this example question to me
Part 1:
If you were solving a system of equations and you came to a statement like 4 = 4, what do you know about the system?
Part 2:
Solve the following system and show all of your work.
3y − 2x = 11
y + 2x = 9

mikala1Best ResponseYou've already chosen the best response.1
2x = 3y  11 so y + (3y  11) = 9 4y = 20 y = 5 5 + 2x = 9 2x = 4 x=2 So x=2 and y=5.

You can check if your answer is correct by putting x=2 and y=5 in your equations and checking if, L.H.S=R.H.S if LHS=RHS then your answer is correct,If not then i am sorry your answer is incorrect
