Example

Example

Solution

The excluded value of a fraction
is the x value
that makes the denominator 0.

The denominator cannot be 0.
So the excluded value
cannot be the solution.

Rational Equation

Rational Inequality

See the given rational expression.

The denominator is 3x - 2.

So set
3x - 2 = 0.

Solve 3x - 2 = 0.

Move -2 to the right side.

Divide both sides by 3.

Then x = 2/3.

So the excluded value is 2/3.
