00:00:00.000 --> 00:00:06.119
Here is the problem: x/(x plus 3) plus 3/(x minus 3) equals 1.

2
00:00:06.569 --> 00:00:07.776
Solve for x.

3
00:00:08.576 --> 00:00:10.016
Start with the equation.

4
00:00:10.466 --> 00:00:23.074
Multiply both sides by x ^ 2 -9 to clear the fractions. This is only valid where x ^ 2 minus 9 not equal to 0, so any value that makes it zero is excluded at the end.

5
00:00:23.524 --> 00:00:26.450
Move every term to one side and simplify.

6
00:00:27.250 --> 00:00:29.224
So the answer is No solution.

7
00:00:29.674 --> 00:00:34.840
The variable cancels and leaves a false statement, so no value of x works.
