Question

Find the value of 'k' for which the system of equation 2x+3y=5 and 4x+ky =10 has infinite number of solution ​

Answer 1

Answer:

2x+3y=5...................1)

4x+ky =10..................2)

in equation 1)

assuming x=1,y=1

2(1)+3(1)=5

2+3=5

putting the value of x and y in equation 2)

4(1)+k(1)=10

k=10-4

k=6
