Solving a Rational Equation

The video tutorial explains how to solve rational equations using the cross multiplication technique. It begins by defining proportions and emphasizes that cross multiplication is applicable only when dealing with proportions. The tutorial then demonstrates the step-by-step process of solving an equation by cross multiplying, applying the distributive property, and simplifying the equation to find the solution. The video concludes with a summary of the method used.

What is a proportion?

• A type of fraction

• A method to solve equations

• A statement that two ratios are equal

• A comparison of two different units

When can the cross multiplication technique be applied?

• When dealing with any equation

• Only when there is a proportion

• When there are no variables

• Only in linear equations

What is the first step in the cross multiplication process?

• Add the ratios

• Multiply across the equation

• Find the least common denominator

• Subtract the ratios

What mathematical property is applied after cross multiplication?

• Identity property

• Associative property

• Distributive property

• Commutative property

What is the final solution to the equation in the example?

• X = -2

• X = 4

• X = 0

• X = 2
