00:01 In this problem, we're given the equation, a equals r plus lowercase a times b.

00:06 And in part a, we're being asked to solve for r.

00:09 In other words, we want to isolate r on either side of the equation.

00:13 Well, let's look at the right -hand side of the equation, where it says r plus lowercase a times b.

00:20 Well, because we're adding ab to r, we need to move that ab term to the other side of the equation.

00:27 Well, what's the opposite of adding ab? well, that would be to subtract ab, and that's exactly what we're going to do.

00:35 So now, on the left -hand side, we have capital a minus lowercase a times b.

00:40 Well, these are not like terms, and therefore cannot be combined.

00:43 So we will simply have capital a minus lowercase a times b.

00:49 Equals, well, on the other side of the equation, we have r, and nothing has happened to that, so that will stay.

00:54 And then we have ab minus ab.

00:57 Well, that's equal to zero, so those will cancel.

00:58 And now we've got an r by itself.

01:01 So we've found that capital a minus lowercase a times b is equal to r.

01:07 Now, for part b, we're given the same equation, except this time we want to solve for a, meaning we want to isolate lowercase a by itself.

01:17 Well, let's again look on the right -hand side of our equation.

01:21 We're adding r to the term a -b.

01:23 We first need to move that r to the other side of the equation.

01:26 Well, what's the opposite of adding r? well, it would be to subtract r.

01:31 And that's what we're going to do first...
