Answer:

x = 16

Step-by-step explanation:

We know that line a and b are parallel so they each have the same slope therefore, (7x + 2) = (8x - 14).

First we have so isolate a number value and x.

So we subtract 7x from 8x, which looks like:

2 = (x - 14)

Then we have to get that -14 to the other side, so we add and that looks like:

16 = x

Therefore, we have our answer, x = 16.
