Comment about following pair of equation:-
2x + 3y = 5
6x + 9y = 6
Answers
Answer:
2x + 3y = 5.....(1)
6x +9y = 6......(2)
2x + 3y -5 = 0......(3)
6x + 9y -6 = 0......(4)
Comparing with ; ; , we get:-
; ;
= =\=
Therefore, The answer is Parallel lines with no solution.
• If a pair of equations are is not equal to then the pair of equations are interesting lines with unique solution.
• If a pair of equations are is equal to is equal to , then the pair of equations are coincident lines with infinitity many solution.
• If a pair of equations are is equal to is not equal to , then the pair of equations are parallel lines with no solution.

Comparing with \frac {a1}{a2} ; \frac {b1}{b2} ; \frac {c1}{c2} , we get:-
\frac {2}{6} ; \frac {3}{9} ; \frac {-5}{-6}
\frac {1}{3} = \frac {1}{3} =\= \frac {5}{6}
Therefore, The answer is Parallel lines with no solution.
\tt {Additional \: Information}
• If a pair of equations are \frac {a1}{a2} is not equal to \frac {b1}{b2}then the pair of equations are interesting lines with unique solution.
• If a pair of equations are \frac {a1}{a2} is equal to \frac {b1}{b2} is equal to \frac {c1}{c2} , then the pair of equations are coincident lines with infinitity many solution.
