Question
CBSEENMA10006837

Write whether the following pair of linear equations is consistent or not.

x + y = 14
x - y = 4 

Solution

x + y = 14
x - y = 4
H e r e comma space space a subscript 1 over a subscript 2 equals 1 comma space space b subscript 1 over b subscript 2 equals negative 1
S o comma space space space space comma space space a subscript 1 over a subscript 2 space not equal to space b subscript 1 over b subscript 2

the equation have unique solution.
Pair of linear equations are consistent.
