Lesson 4 Skills Practice Guide for Solving Two Step Equations

Isolate the variable by reversing operations in a fixed order: remove constants first, then undo multiplication or division. Writing each move on a separate line reduces sign errors and keeps transformations easy to verify.

Check each result by substitution. Replace the variable in the original statement and confirm both sides match numerically. This habit quickly exposes mistakes with negatives, fractions, or distribution.

Review completed work step by step using the provided worked results. Focus on operation order, balance on both sides, and clean notation to improve accuracy on future algebra drills.
