4x + 2x = < y
This is because the opposite sides (which is 4x and 2x) of a triangle add up to the exterior angle (<y).
We have to find X.
As you know:

because the angles of a triangle add up to 180.
When we add them:


The 9 is multiplying with the X. We want X only and not 9 with it. So, when we take 9 to the other side, it becomes divide. As a result, the answer to x is:-

Substitute value of x into 4x and 2x to find the exterior angle:-
4x:

2x:

When we add them we get the answer for angle Y:-

Therefore, we can conclude that:

Prettyyyyyy sure it’s the 2nd one
