I’m confused on this one

Murrr4er [49]

This one is a bit confusing without a diagram anyway. We'll assume the typical labeling where A and B are consecutive angles, so the transverse line AB through the parallels makes A and B supplementary:

A + B = 180 degrees

12x + 46 + 7x + 1 = 180

19x = 180 - 47 = 133

x = 133/19 - 7
