Single fractions set equal to each other forms a proportion. When presented with this, it can be "cross multiplied" to eliminate the fractions. The resulting equation has a term with the…

|
This has two examples so that you can learn to watch out for what looks like a solution but is not because it creates division by zero if you check the answer in the original equation. The other…

Demonstrates multiplying each term in a rational equation by the least common denominator of all fractions so that the denominators can be eliminated and the resulting linear equation can then be…

|
Shows cross multipication of two single fractions set equat to each other to create a new equation that has no fractions and is then solvable by the typical methods.
|
|
This type of equation is solved by factoring a GCF from both terms once the proper form is achieved. Then the zero product property allows the separation of the two factors into two solvable linear…

Shows how to factor the greatest common factor from a simple linear binomial
|
|
This demonstrates testing possible answers to a system of two equations to see whether they are truly answers or not. Note that each answer has to work for both equations, but if it doesn't…
