Solving Absolute Value Equations

The video tutorial explains two methods to solve absolute value equations involving two absolute values. It demonstrates solving the equations X - 3 = 2x + 10 and X - 3 = -2x - 10 separately, providing step-by-step instructions. The solutions are verified by substituting them back into the original equations. The tutorial concludes with a brief mention of a related video for solving equations with one absolute value.

What are the two methods mentioned for solving the problem?

• Using substitution and elimination

• Using quadratic formula and factoring

• Graphical method and algebraic method

• Setting the equation equal to positive and negative values

What is the first step in setting up the equations?

• Adding 3 to both sides

• Subtracting 2x from both sides

• Setting the equation equal to positive and negative values

• Multiplying both sides by negative one
