Q which of the ordered pairs of numbers (7,13),(8,-2),(2,-6),(3,9) is a member of the solution set of x+y=6?

Dear Student,The equation is x+y=6In order for a pair of x,y, to be a solution of the equation.It must satisfy the above equationFor eg:- order pair 7,1   i.e. x=7 , y=1gives  7+16Hence this order pair is not the solution.order pair 8,-2i.e.  x=8, y=-2Gives 8+-2=66=6Hence, It satisfy the equation.Therefore 8,-2 is the required solution.Regards.
