Step-by-step explanation:

step 1. I guess we assumed the two lines across the transversal are parallel

step 2. 3x + 1 = 85 (definition of alternate exterior angles)

step 3. 3x = 84 (subtract 1 from each side)

step 4. x = 28. (divide both sides by 3)

B - 7x = a - b
Subtract b from both sides.

-7x = a - 2b
Divide both sides by -7.

x = $\frac{-a + 2b}{7}$
