This week in pre-calculus, we learned how to solve rational equations. We can cross multiply when there are two fractions on both sides of the equal sign, but when there are more than two fractions, you would have to find the common denominator and multiply each side to get rid of the denominator to solve the equation. In both situations, remember to double check to verify the answer.

Cross Multiplication

steps

1. cross multiply (top left with the bottom right and vice versa)
2. isolate the x value
3. plug it back into the original equation to confirm

More than 2 Fraction

steps

1. find the common denominator
2. cancel out the denominators
3. isolate the x value
4. verify the solution by plugging it back into the original equation
