Answer:

Explanation:

To find x:

1) Substitute 0 for y.

3x - 0 < 5

The zero doesn't really matter so you can get rid of it.

3x < 5

2) Divide by 3 to get x by itself

3x/3 < 5/3

x < 5/3

or

x < 1 2/3

To find y:

1) Substitute 0 for x.

3(0) - y < 5

3 times 0 equals zero so you can get rid of it.

-y < 5

2) There is an invisible 1 in front of the -y. So you divide by -1 to get y by itself.

-y/-1 < 5/-1

y < -5
