Fins the calue if 'k' which of the following system of linesr equation have infinite number of solutions2x + ky=3 (k+x) X+ 25y = 2k+5​

Answer»

2. k. 3

-----=------=-------

(k+x) 25. 2k+5

50=k^2+kx*--(i) , 2k^2+5k=75---(II)

from eq. (ii),

2k^2+5k-75=0

2k^2+30k-5k-75=0

2k(k+15)-5(k+15)=0

2k-5=0. k+15=0

k=5/2. k=-15

bhai BHOT mehnat lagi hai type KARNE me plz like kar diyo
