Ha ha ha..

Oh sorry its @minya ..

See here:

Add 2x both the sides first:

$$2x + y < 3$$

Now you can do here one thing only:
Substitute values from the choices given and check which is not coming  right..

For example your first option is : $(-1, 3)$

So put x = -1 and y = 3 you will get:

$$2(-1) + 3 < 3$$
$$3 - 2 < 3 \implies 1 < 3 \; \; (True)$$

So first option is not right..

Similarly try to plug in second third and fourth option and find where $2x + y > 3$ you are getting..

you can also graph the inequality and plot your points, if the point is in the shaded region then it is a solution.
