Question

Write whether the following pair of linear equations x + y = 14, x – y = 4 has unique solution, infinitely many solution or no solution​

Answer 1

Answer:

INFINITELY MANY SOLUTIONS

AT x=0

0+y=14

y=14

AT Y=1

x-1=4

x=4+1

x=5

AT Y=0

x+0=14

x=14

AT X=0

0-Y=4

-Y=4

Y=-4

Answer 2

Write whether the following pair of linear equations x + y = 14, x – y = 4 has unique solution, infinitely many solution or no solution
