The pair of angles given are alternate angles (they form a 'Z' shape). Alternate angles are always equal to each other. From this, we can get the equation:

14x - 13 = 8x + 5

Collect like terms,

6x - 13 = 5

6x = 18

x = 3

Hope this helped!! Ask me if there's any part of the working you don't understand :)
