3x equals negative y minus 6 we need to complete the ordered pairs first number and ordered pair is x second number is y so this is the same x is now zero, so i'm going to plug that in three times zero equals negative y minus six three times zero is zero and i need to figure out what y is equal to so i'm going to solve for y by adding six to both sides so six equals negative y that's negative one 1 y, so divide by negative 1 to get y by itself.

U -due, multiply, and you divide.
00:40
So we have y equals negative 6.
00:45
Next up, the 0 is in the second spot in order to pairs.
00:50
That means i plug 0 in for y now.
00:53
So we've got 3x equals negative y, so that's negative 0 minus 6.
01:02
3x, negative 0 minus 6 is negative 6, 3x, times x so to undo multiplication you divide so x equals negative 2 and the last one third is in the first spot so that's the x 3 times negative 1 3rd needs to equal negative y minus 6 3 times negative 1 3 times negative 1 3 we need to give it a subtracting 6 so so we add six to both sides.

5 equals negative y.
01:43
That's negative 1.
01:44
So divide both sides by negative 1.
01:47
So negative 5 equals y...
