Question

if a pair of liner equations x+ 2y =3 and 2x+4y=k
arecoinciding then the vale of 'k'
​

Answer 1

Answer:

${\huge{\mathtt{\green{\ answer}}}}$

The condition for coincident lines is a1/a2=b1/b2=c1/c2. Here, to satisfy the condition, k will be 6.

Answer 2

Answer:

First balance the equation and go for elimination method .There you will obtain k-6=0 .By sending -6 to the RHS side you will obtain the value of K is 6. Hence the answer is 6
