Solving Multi-step Equations by Combining Like
Terms and withVariables on Both Sides

  • Getting rid of fractions.
  • To get rid of a fraction from an equation
    multiply each term by the LCD.
  • Getting rid of parentheses.
  • To get rid of parentheses from an equation,
    distribute.
  • Getting rid of like terms that are on the same
    side of the equal sign.
  • Combine like terms by adding or subtracting using
    your integer rules.
  • Simplifying equations involves three steps.

This lesson focuses on this part.

Ex. 1
  • To SIMPLIFY use this checklist.
  • Any fractions?
  • NO
  • Any ( )
  • NO
  • Any like terms
  • YES use integer rules.
  • Now SOLVE

  • To SIMPLIFY use this checklist.
  • Any fractions?
  • NO
  • Any ( )
  • NO
  • Any like terms
  • YES Combine them using Integer rules.
  • Now ISOLATE the variable
  • and SOLVE

5
  • To SIMPLIFY use this checklist.
  • Any fractions?
  • NO
  • Any ( )
  • NO
  • Any like terms
  • NO
  • So ISOLATE the variables. Get them together on
    the same side
  • Now SOLVE
  • And reduce
