Comment about following pair of equation:- 2x + 3y = 5 6x + 9y = 6​

Answer»

Answer:

\bold {According \: to \: Question}

2x + 3y = 5.....(1)

6X +9y = 6......(2)

2x + 3y -5 = 0......(3)

6x + 9y -6 = 0......(4)

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.

• If a pair of equations are \frac {a1}{a2} is equal to \frac {b1}{b2} is not equal to \frac {c1}{c2} , then the pair of equations are parallel lines with no solution.
