Question

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

x + y = 4 and x – y = 4​

Answer 1

Answer:

Step-by-step explanation:

fr consistent pair of equation whether:

a1/a2 is not equal to b1/b2

            or

a1/a2=b1/b2=c1/c2

let us check

 a1=1;b1=1;c1=4

 a2=1;b2=-1;c2=4

as a1/a2is not equal to b1/b2 the eqution has a consistent solution
