Isolating Absolute Value Equations

The video tutorial explains how to solve an absolute value equation for x. It begins by isolating the absolute value expression, then proceeds to solve the equation by removing the absolute value and simplifying the expression. The final solution is found by isolating x and performing basic arithmetic operations.

What is the first step in solving an absolute value equation?

• Add a constant to both sides

• Isolate the absolute value term

• Multiply both sides by a constant

• Square both sides

What is the purpose of isolating the absolute value term in an equation?

• To simplify the equation

• To make the equation more complex

• To eliminate the variable

• To find the solution directly

What is the significance of the absolute value in an equation?

• It represents a positive value

• It represents a negative value

• It represents both positive and negative values

• It represents zero

What operation is performed to both sides to start isolating the absolute value term?

• Adding 4

• Dividing by 4

• Subtracting 4

• Multiplying by 4

After subtracting 4, what is the next step to isolate the absolute value term?

• Multiply by -3

• Subtract 3 from both sides

• Divide by -3

• Add 3 to both sides

What is the result of dividing zero by negative three?

• Negative three

• Zero

• Undefined

• Three

What happens to the equation when you divide both sides by a negative number?

• The equation becomes zero

• The equation remains unchanged

• The equation becomes negative

• The equation becomes positive

When can you drop the absolute value in an equation?

• When the other side is a fraction

• When the other side is negative

• When the other side is zero

• When the other side is positive

What does 5x + 1 equal after dropping the absolute value?

• Five

• Zero

• One

• Negative one

Why is it important to check if the other side of the equation is zero before dropping the absolute value?

• To ensure the solution is valid

• To ensure the solution is a fraction

• To ensure the solution is negative

• To ensure the solution is positive
