Add and to get.

Reduce the expression by cancelling the common factors. Cancel the common factor. Set up the rational expression with the same denominator over the entire equation. Multiply each term by a factor of that will equate all the denominators.

In this case, all terms need a denominator of.

The expression needs to be multiplied by to make the denominator. Multiply the expression by a factor of to create the least common denominator LCD of. Since the expression on each side of the equation has the same denominatorthe numerators must be equal. Rewrite the equation as.

Divide each term by calculatoe simplify. Divide each term in by. Divide by to get. Check that all solutions found are valid and are part of the domain by substituting them into the original equation.

Quick-Start Guide The calculator uses cross multiplication to convert proportions into equations which are then solved using ordinary equation solving methods. Use the following as a guide: Variables Any lowercase letter may be used as a variable. Parentheses and Brackets Parentheses and brackets [ ] may be used to group terms as in a standard equation or expression. Order of Operations The calculator follows the standard order of operations taught by most algebra books - Parentheses, Problfm, Multiplication and Division, Addition and Subtraction.

Special Note If either side of the proportion has a numerator and denominator that share a common factor with a variable, the calculator will report an erroneous solution.

They are sometimes referred to as "cases. Moreover, if you choose a case that disconfirms a theory, you should be careful that the case falls within the scope conditions see above of the given theory.
