Question

write whether the following pair of linear equation is consistent or not
X+Y=14, X-Y=4​

Answer 1

Answer:

the following equation is consistent.

Step-by-step explanation:

because a1/a2 if not equal to b1/b2.

Answer 2

Answer:

no,it is not

Step-by-step explanation:

x+y=14     -eq 1

x-y=4      -eq 2

x=4+y   -eq 3

from 1 and 3,

4+y+y=14

2y=10

y=5        -eq 4

from 4 and 3,

x=4+5

x=9       -eq 5

from 5 and 1,

5+4 is not equal to 14

9 is not equal to 14
