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

    For part 1 If such situations occur there is no solution For part 2 There are 2 methods 1) Substitution 2)Elimination

    is it 3y -4x=20

    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
