Step 3. Upload or paste your screenshot to the Formative canvas.

If you need a reminder of how to complete Step 1, review this video from the Desmos team and/or see Problem 3 from the Lesson 2-5 slideshow.

Review Lesson 1-6: Resequence the items below to indicate the correct procedure for solving the absolute value equation.

1. Isolate the |x - 3| part of the expression by subtracting 2 from each side of the equation.
2. Since both solutions satisfy the equation, they are both solutions of the equation.
3. Solve the two equations separately to find two possible solutions: x = 8 and x = -2.
4. Separate the equation |x - 3| = 5 into two equations: x - 3 = 5 and x - 3 = -5.
5. Check both possible solutions by substituting them into the original equation, |x - 3| + 2 = 7.

Review Lesson 1-6: Fill in the blank: When solving absolute value equations, a possible solution that does not check out when substituted into the equation is called a(n) __?__.
