A complete formative lesson with embedded slideshow, mini lecture screencasts, checks for understanding, practice items, mixed review, and reflection. I create these assignments to supplement each lesson of Pearson's Common Core Edition Algebra 1, Algebra 2, and Geometry courses. See also mathquest.net and twitter.com/mathquestEDU.

Review Lesson 2-3: Match each solution with the appropriate equation(s).
x = -2
x = 16
x = -8
3x + 7 = 2x - 1
x รท 2 + 5 = -x + 2
4(x - 3) = 20 + 2x
x + -8 = 2x
