Write an equation (in terms of x) to represent the relationship between the angles shown. What is the number for X in said equation

The equation that represents the relationship between the given angles is x+14=3x-16. And the values of X is equal to 15.
Some angles receive a special classification according, for example: the sum between them and their positions. See examples:
The given angles can be classified as alternate angle because are in opposite positions relative. Thus, they will have the same measure. Thus,
x+14=3x-16
3x-x=14+16
2x=30
x=15
If x=15, the angle x+14 will be 15+14=29°. And, the angle 3x-16 will be 45-16=29º.
