Question

X - 3y = 9, complete the ordered pair (12, ).

Answer 1

(12,1)

Explanation:

In the ordered pair, x=12

plug 12 back in the equation

12-3y=9

-3y=-3

3y=3

y=1

Answer 2

(12,1)

Explanation:

We know that ordered pairs are in the format of (x,y).

This means in that (12, __) 12 is our x coordinate. Plugging 12 into the equation as x we get:

`12-3y=9\\-3y=9-12\\-3y=-3\\y=1`

Therefore our answer is (12,1) as we plug y back into our coordinate (x,y).
