    the sum of all angles on a straight line should add up to 180 degrees

    you cant "solve" it. there are infinite possibilities for x and y. The trick here is that the question is asking you for only "integer values" of x and y. They have given you several options for the value of "y". so your job is to substitute the value of "y" from each option, and solve the equation "x" , and see which option gives you an integer value for x. only one option gives an integer value, the other give fractions.

    i'm sorry, the have given you options for "x", so substitute and solve for "y"
