Question 3
If (2, 0) is a solution of the linear equation 2x + 3y = k, then the value of k is:


A) 4
B) 6
C) 5
D) 2

Answer 1

The answer is A.
Since (2,0) is a solution of the given linear equation 2x+3y = k,
put x = 2 and y = 0 in the equation.
$\Rightarrow$ 2(2)+3(0)=k $\Rightarrow$ k = 4
Hence, the value of k is 4.
