  24. Solve Steps • Word Problems • Draw – picture, graph, table • Known- from inside and outside the problem • Unknown – what are you being asked to find • Relationship – between known and unknown • Solve • Answer: Does it make sense? Plug it back in

  25. Solve Steps • Use GEMDAS - work one side then the other • Isolate the variable - when there is nothing left to do on either side • Use one variable to solve for the other(s) - for a system

  26. Solve Steps • Read and write down the problem • Ask yourself - What do I do next? • Think - about what you know
