Question

X-2y=7; ( ,2) (,1) complete each ordered pair so that is a solution of the given linear equation.

Answer 1

To complete each ordered pair, you would have to substitute the 1 and 2 in for y. Let's start with the 2 first. X-2(2)=7, x-4=7. Add 4 on each side. X=11. First ordered pair is (11,2). Now do the 1. X-2(1)=7, x-2=7. Add 2 on both sides. Second ordered pair is (9,1). Answers are (11,2) and (9,1)

Answer 2

Answers are (11,2) and (9,1)
