About This Worksheet

This hard-level worksheet contains 27 problems designed for 8th Grade students practicing variables on both sides. Hard worksheets feature challenging problems including multi-step questions, missing values, and real-world applications to push students further.

Variables on both sides mark a major step in algebraic sophistication. This equation type appears in applied mathematics, physics, and economics whenever two changing quantities are set equal — a structural pattern that recurs throughout STEM.

  • Collect all variable terms on one side and constants on the other
  • Apply the distributive property before solving
  • Recognize when an equation has variables on both sides and plan a solution strategy
  • Model rate and cost problems that naturally produce variables on both sides
  • Identify equations that lead to no solution or infinitely many solutions
