Question

1. Which of the following pair of linear equations
has unique solution, no solution, or infinitely
many solutions.
(1) 5x + 7y + 12 = 0 (11) x - 34 -7 = 0
15x + 219 + 36 = 0 3x - 2y + 16 = 0
(iii) 2x + 5 = 17 (iv) 3x - 5y = 20
5x + 3y = 14
6x - 101 - 40=0
​

Answer 1

answer....

1. ratio= 1/3=1/3=1/3...

so it have infinite many solutions 2.ratio.=1/3 is not = 3/2

so it have unique solution

3.have unique solution &

4.also have a unique solution
