Answer 2

Answer:

k≡6

Step-by-step explanation:

Concept

An algebraic equation can be defined as a mathematical statement in which two expressions are set equal to each other.

Given

kx+2y=5

3x+y=1

Find

Value of k

Solution

$k x+2 y=5$

$3 x+y=1$

Condition for unique solution is

$\frac{a_{1}}{a_{2}} \equiv \frac{b_{1}}{b_{2}}$

$\Rightarrow \frac{k}{3} \equiv \frac{2}{1} \Rightarrow \mathrm{k} \equiv 6$
