no is not write ,if you use graphical method and solved correctly ,then it will never wrong.

THANKYOU

mani863: if we assume x and y sometimes graph dont give right answer what is the method.

Answered by CLASHOFDEMONS

Graphical method sometimes goes wrong-

●Not correct plotting

●If there no unique solution

●Cannot take out the vertices

So best is elimination,Subsitution or Cross multiplication

Hope it helps

mani863: Our assuming of x and y is right for equation but doesn't give correct plots for solutions

CLASHOFDEMONS: yeah

CLASHOFDEMONS: because it can be infinite solutions or no solutions

mani863: if no solution how does line intersect

CLASHOFDEMONS: parallel

CLASHOFDEMONS: they do not intersect
