 Hi and welcome to the session. Let's discuss the following question. The question says write four solutions of the following equation pi x plus y is equal to 9. Let's now start the solution when x is equal to 1 then the given equation reduces to into 1 plus y is equal to 9 right and this implies Y is equal to 9 minus pi so x is equal to 1 and y is equal to 9 minus pi is a solution of the given linear equation When x is equal to 0 then the given linear equation reduces to pi into 0 plus y is equal to 9 and this implies y is equal to 9 therefore x is equal to 0 and y is equal to 9 is a solution of the given linear equation right now When x is equal to minus 1 Then the given linear equation reduces to pi into minus 1 plus y equals to 9 and this implies minus pi plus y is equal to 9 and this implies that y is equal to 9 plus pi therefore x is equal to minus 1 and y is equal to 9 plus pi is a solution of the given linear equation right now When x is equal to 9 upon pi then the given linear equation reduces to pi into 9 by pi plus y equals to 9 and This implies 9 plus y is equal to 9 and this implies y is equal to 0 so x is equal to 9 by pi and y is equal to 0 is a solution of the given linear equation Hence the four required solutions are 1, 9 minus pi 0, 9 minus 1, 9 plus pi and 9 by pi 0 This is our required answer. Bye and take care. Hope you have enjoyed the session you
