Choose the equivalent system of linear equations that will produce the same solution as the one given below.

4x - y = -11
2x + 3y = 5

-4x - 9y = -19
-10y = -30

4x + 3y = 5
2y = -6

7x - 3y = -11
9x = -6

12x - 3y = -33
14x = -28

have you any idea, how will we solve this...?

anonymous · Answer

not really... I been studying this for days but I don't get it

paki · Answer

solve the below equations for x and y... then put these values in the all other equations... and the value which get the both sides equal is the required equation.... 
4x - y = -11
2x + 3y = 5
