Answer:

x = 7

Step-by-step explanation:

The angles (6x - 7) and (4x + 7) are the vertical angles.

The vertical angles are congruent, therefore have the same measure.

We have equation:

6x - 7 = 4x + 7            subtract 4x from both sides

6x - 2x - 7 = 4x - 2x + 7

2x - 7 = 7      add 7 to both sides

2x - 7 + 7 = 7 + 7

2x = 14        divide both sides by 2

2x : 2 = 14 : 2

x = 7
