If L (3x + 50 degrees)is parallel to M (2x  20 degrees) find X.

What is L and M? Lines? IF so, what is this degree business in the parenthesis?
If L and M are angles, how can angles be parallel.
I can make no sense of what you posted.

I assume you mean
the slope of Line L = 3x+50
the slope of line M = 2x20
If the lines are parallel, the slopes are equal. So,
3x+50 = 2x20
x = 70
