Rearranging Equations and Subject Terms

This video tutorial explains how to rearrange equations to isolate a specific variable, making it the subject. It covers the process step-by-step, starting with removing fractions and brackets, collecting subject terms, factorizing, and finally isolating the variable. Two examples are provided: one for making x the subject and another for making b the subject. The video concludes with tips and emphasizes the importance of practice to master the technique.

What is the main challenge when rearranging equations to make a letter the subject?

• The subject appears more than once.

• The subject appears only once.

• The equation is already simplified.

• There are no fractions involved.

What is the first step in rearranging an equation to make a letter the subject?

• Divide both sides by a constant.

• Remove any fractions or brackets.

• Factorize the equation.

• Collect all terms on one side.

In the first example, what operation is performed to eliminate the brackets?

• Addition

• Subtraction

• Multiplication

• Division

What defines a subject term in an equation?

• Any term without a variable.

• Any term with the subject letter.

• Any term with a constant.

• Any term with a fraction.

What is the purpose of factorizing the subject terms in an equation?

• To isolate the subject letter.

• To simplify the equation.

• To eliminate fractions.

• To add more terms.

In the second example, what is the first step to eliminate the fraction?

• Add a constant to both sides.

• Multiply both sides by the denominator.

• Subtract the numerator from both sides.

• Divide both sides by a constant.

What is the result of expanding the bracket in the second example?

• A single term.

• A simplified fraction.

• Two separate terms.

• A constant value.

How do you move a term from one side of the equation to the other?

• By adding it to both sides.

• By subtracting it from both sides.

• By multiplying it by both sides.

• By dividing it by both sides.

What is the final step to isolate the subject in an equation?

• Multiply both sides by a constant.

• Add a constant to both sides.

• Divide both sides by the factorized term.

• Subtract a constant from both sides.

Why might you not need to follow the exact steps in every equation?

• Some equations are already solved.

• Different equations may require different approaches.

• The steps are only for complex equations.

• The steps are optional.
