Solve the rational equation:
Solve the rational equation:
With rational equations we must first note the domain, which is all real numbers except 
and 
. That is, these are the values of 
that will cause the equation to be undefined. Since the least common denominator of 
, 
, and 
is 
, we can mulitply each term by the LCD to cancel out the denominators and reduce the equation to 
. Combining like terms, we end up with 
. Dividing both sides of the equation by the constant, we obtain an answer of 
. However, this solution is NOT in the domain. Thus, there is NO SOLUTION because 
is an extraneous answer.

Combine like terms on each side of the equation:
Next, subtract 
from both sides.
Then subtract 
from both sides.
This is nonsensical; therefore, there is no solution to the equation.

How many solutions does the equation below have?
How many solutions does the equation below have?
When finding how many solutions an equation has you need to look at the constants and coefficients.
The coefficients are the numbers alongside the variables.
The constants are the numbers alone with no variables.
If the coefficients are the same on both sides then the sides will not equal, therefore no solutions will occur.
Use distributive property on the right side first.

terms can be eliminated.
Subtract one on both sides.
However, let's substitute this answer back to the original equation to check whether if we will get 
as an answer.
Simplify the left side.
The left side does not satisfy the equation because the fraction cannot be divided by zero.
Therefore, 
is not valid.
