    First, recall the ways to prove lines parallel. See the attached chart.

    I agree. Look at this. The two angles marked in blue are same-side interior angles. Theorem: If two lines are cut by a transversal so that same-side interior angles are supplementary, then the lines are parallel.

    So, you have an equation to solve: 45x - 5 + 16x + 2 = 180

    45x - 5 + 16x + 2 = 180 Combine the like terms on the left. What do you get?

    Yes, that is what I got. Now, we have to get y.

    and to get y do we combine the terms on the right?

    I'm looking at these angles marked in red. They are supplementary because they are two adjacent angles whose exterior sides form a line. So, 16x + 2 + 26y = 180 16*3 + 2 + 26y = 180 Solve that ^ for y. Note that I replaced the x by 3 because that is what you solved for earlier.

    Yes. It would be easy to get mixed up and put a). It is a good idea to double-check.
