Question

write whether the following pair of linear equations is consistent or not x+y=14, x-y=4​

Answer 1

Step-by-step explanation:

x-y=4.......(i)

x+y=14

x=14-y

Substitute the value of x in (i), we get;

(14-y)-y=4

14-y-y=4

14-2y=4

14-4=2y

10=2y

5=y

Now putting the value of y in (i) ,we get ;

x-5=4

x=4+5

x=9

Value of x=9 &y=5

Answer 2

Answer

they are not consistent i.e inconsistent.
