Hi Mate !!

• For an equation to be independent the Relation between it's coefficient of x and coefficient of y with another equation should be as follows :-


$\frac{a1}{a2} \: \: \: \: not \: equal \: to \: \: \: \frac{b1}{b2}$

Given equation :- x + 2y = 3
5x + ky + 7 = 0

Here , a1 = 1 b1 = 2
a2 = 5 b2 = k


$\frac{1}{5} \: \: \: not \: equal \: to \: \: \frac{2}{k}$

1/5 ≠ 2/k

k ≠ 10


So , for any value of k accept 10 the equation will be independent !!
