We're going to check and see if the proposed solutions to the equations are actually solutions to the equation.

X minus a over x minus b is equal to a over b for all values where b does not equal zero.
00:15
So to do this, we are going to plug in our first proposed value for x, which is zero.
00:22
Everywhere we see in x, we're going to replace it with a zero.
00:25
So we have zero minus a over zero minus b is equal.
00:31
To a over b.
00:36
So on the left side, 0 minus a is going to give us negative a over negative b, which is equal to a over b.
00:52
Our negative signs actually just cancel out.
00:55
So on the left, we have a over b is equal to a over b.
00:59
And this checks out...
