PLS HELP ME WITH MY GEOMETRY GUYS PLS

Answer 1

Answer:

(6, 3)

Step-by-step explanation:

x=6 y=3

2(6) -3 =9

12 -3 = 9

Answer 2

Answer:

(3,-3)

but there are infinately many more.

Step-by-step explanation:

We need to find a pair of numbers that when substituted in 2x-y we get 9.

because this equation is linear there are actually an infinite number of solutions. So all we have to to is pick a random number for x, say 3, and there will only be 1 value of y that will satisfy the equation, so we just plug it in.

let x =3

2x - y = 9 ⇒ 2×3 - y = 9

                ⇒ 6 -y = 9

                ⇒ -y = 3

                ⇒ y = -3

so (3,-3) is a solution
