Question

For all real values of C the pair of equations x-
2Y=8 and 5x-3Y=c have unique solution justify whether it's true or false

Answer 1

Answer:

WE KNOWW THAT IN UNIQUE SOULTION

==> A1/A2 ≠ B1/B2≠ C1/C2

==> S0,    1/5 ≠ 8/C  AND  2/-3 ≠ 8/C

==>  5 ≠ C/8  AND -3/2 ≠ C/8

==> 40 ≠ C AND -3*8/2 ≠ C

==> C ≠ 40 AND -12

SO, EXCEPT 40 AND -12 . C BE ANY VALUE
