Question

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


pls fastt ​

Answer 1

Concept :

$\tt If ( {x}_{1} , {y}_{1} )\: is \: a \:solution\: of \: the \: linear \: equation \\ \tt \: ax + by + c = 0 \: then \: a{x}_{1} + b{y}_{1} + c = 0$

Solution :

( 2 , 0 ) is a solution of the liner equation 2x + 3y = k

so 2(2) + 3(0) = k

4 + 0 = k

k = 4

$\boxed{\underline{\bold{\red{\tt k = 4 }}}}$
