Solve for c in this equation a(b-c)=a/b

The problem is asking us to isolate . This means that we are going to want to get on its own side, with no other variables or terms. We can see that there is both an and on the side of the equation with , so our goal will be to remove those.

To get rid of the , let's divide both sides of the equation by . This gives us:

Now, we are still going to have to remove the . To do this, let's subtract a from both sides of the equation. This gives us:

Finally, let's multiply both sides of the equation by -1. This will remove the negative sign before the term on the left side. This gives us:

Our answer is

the first one, all those points on the line just make a strait line.

- (2, -7)

- lines r and s and lines t and u must be parallel
