Y = 4x-9

and y=x-3

Also using transitive property

Y = 4x - 9 and y = x-3 so the two right sides (4x-9 and x-3) must be equal

4x-9 = x-3

Let's solve for x

4x-9 = x-3

4x-9+9 = x-3+9 ... add 9 to both sides

4x = x+6

4x-x = x+6-x ... subtract x from both sides

3x = 6

3x/3 = 6/3 ... divide both sides by 3

x = 2

If x = 2, then y is ...

y = 4*x - 9 = 4*2-9 = 8-9 = - 1

which can also be found by

y = x-3 = 2-3 = - 1

So overall x = 2 and y = - 1

We have the ordered pair (x, y) = (2,-1)
