The pair of angles would be corresponding angles, as they correspond to each other, meaning they occupy the same side of the transversal and at the same time, "face" the same side. Since corresponding angles are equal, we have to solve for x using isolation.
[tex]18x+4=130\\ 18x+4-4=130-4\\ 18x=126\\ \frac{18x}{18} =\frac{126}{18} \\ x=7[/tex]
In that case, x is equal to 7.
