Question

draw graph of linear equation 3x- 7y=21 check (8,1) is a solution of given equation​

Answer 1

Answer:

(8,1) not a solution of 3x-7y=21

Step-by-step explanation:

eqn:- 3x-7y=21

putiing given value of x and y in it

or , 3* (8) - 7*(1) =21

". , 24-7=21

, 17=21

hence , 17 is not equal to 21 ,so it is not a solution of given equation.
