## Answers

The result should be 3.

To solve this re-write the equation so that it reads y= and then plug in the 2 from the coordinate and then solve for y. or you can just plug in the 2 for x and solve for y, either way works and you get that y is 3, which means that the coordinate is (2,3)

(6.2)-7y=-9

12-7y=-9

-7y=-9-12

-7y=-21

y=-21/-7

y=3

6.2-7y=

(x,y) form

therefor

x=2 and y=? is one solution that is true

subsitue 2 for x and ? for y

6(2)-7(?)=-9

multiply

12-7?=-9

subtract 12 from both sides

-7?=-21

divide both sides by -7

?=3

(2,3)

here, x = 2

putting the value of x in the equation we get:

6x-7y=-9

or, 6×2- 7×y=-9

or, 12- 7×y= -9

or, 7×y =-21

so, y = -3
