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

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) __?__.
