Solving Absolute Value Equations

The video tutorial explains how to solve an equation involving absolute values. It begins by rewriting the equation to highlight the absolute values, then simplifies the equation by isolating the absolute value expression. The tutorial demonstrates solving for the absolute value of x plus 7, and finally, it finds the possible values of x by considering both positive and negative scenarios. The solutions to the equation are determined to be negative 48/7 and negative 50/7.

What is the first step in solving the given equation?

• Rewriting the equation to highlight absolute values

• Directly solving for x

• Ignoring the absolute values

• Multiplying both sides by a constant

How can the absolute value expression be treated to simplify the equation?

• As a polynomial

• As a fraction

• As a variable

• As a constant

What operation is performed to isolate the absolute value expression on one side?

• Exponentiation

• Multiplication and division

• Taking the square root

• Addition and subtraction

After isolating the absolute value expression, what is the next step?

• Solving for x directly

• Dividing both sides by the coefficient

• Multiplying both sides by a constant

• Adding a constant to both sides

What is the simplified form of the equation after dividing by 14?

• Absolute value of x plus 7 equals 0

• Absolute value of x plus 7 equals 1/7

• Absolute value of x plus 7 equals 14

• Absolute value of x plus 7 equals 2

What are the two possible scenarios for the absolute value expression?

• Positive and zero

• Positive and negative

• Zero and negative

• Zero and positive
