It is important to check your answers to make sure that it doesn't give a zero denominator in the original equation. When we multiply both sides of an equation by the LCM the result might have solutions that are not solutions of the original equation. We have to check possible solutions in the original equation to make sure that the denominator does not equal zero. There is also the possibility that calculation errors were made in solving.

What are the steps in solving rational equations?
1. First we need to determine the least common denominator of the fractions in the given rational equation. 2. We need to take out the fractions by multiplying All terms by the least common denominator. 3. Then we have to simplify the terms in rational equation. 4. Solve the resulting equation. 5. Check the answers to make confident the solution does not make the fraction undefined.
What is the result of solving an equation?
It is the solution of the equation
What do you do when solving an equation?
5R=45
When solving a rational equation why it is OK to remove the denominator by multiplying both sides by the LCD and why can you not do the same operation when simplifying a rational expression?
You can multiply both sides by the LCD because as a rule, you can do anything to one side of an equation as long as you do the same thing to the other side. But when you simplify a rational EXPRESSION, you don't have an EQUATION. So there is no other side. So you can't multiply both sides by anything. You can, however, multiply both the numerator and the denominator by the same term (except zero).
How does solving a literal equation differ from solving a linear equation?
Because linear equations are based on algebra equal to each other whereas literal equations are based on solving for one variable.
When solving a rational equation why is it nessecary to perform a check?
to see ifyou made any mistakes
What is the definition of solving a rational equation?
to find the unknown variables
When solving a rational equation what is the first step you must always take?
Get rid of the denominator.
Can the five steps for solving rational equation be eliminated?
no. an individual step might be, but not all.
When solving an algebraic equation which operands do you perform first?
In algebra, you perform the operations inside parentheses first.
Can any steps to solving a rational equation be eliminated?
Yes, but it depends on your mathematical skills and confidence.
What method is used for solving a rational equation?
Methods vary considerably depending upon the number of powers in the equation. For example, the method for solving cubics is quite different to solving quadratics etc... It's not really possible to generalise to one technique.
Can you change any of the steps for solving a rational equation?
Yes. Since "these" do not exist, cjanging them should not make a difference.

What role of operations that applies when you are solving an equation does not apply when your solving an inequality?
What role of operations that applies when you are solving an equation does not apply when your solving an inequality?"
Do you never balance and equation when solving?
No because you always keep an equation in balance when solving it
What is another example of the five steps in solving rational equation?
"another" implies that you already have one example. In order to answer the question it might just help to know what that is.
