The relevant fact about vertical angles is that they are congruent, their measures are equal. This lets you write an equation relating the expressions for the measures of angles A and B.

∠A = ∠B

(8x -12)° = (6x +14)° . . . . . substitute given expressions

2x = 26 . . . . . . . . . . . divide by °, add 12-6x

x = 13 . . . . . . . . . . divide by 2
