Question

check whether (2,1)is the solution of the equation x-2y=4​

Answer 1

Answer:

Here is your answer mate .

Step-by-step explanation:

$putting \: x \: = 2 \: and \: y = 1 \\ 2 - 2(1) = 4 \\ 2 - 2 = 4 \\ 0 = 4 \\ it \: \: is \: not \: thesolution \: of \: the \: given \: equation$

Hope it will help you

Answer 2

Answer:

no it's not the solution

x = 2 , y = 1

=> (2) - 2(1) = 4

=> 2 - 2 = 4

=> 0 = 4 which is not possible , so (2,1) is not the solution of the equation x-2y=4

hope this helps you
