  1. Combine like terms: Combine like terms by adding the coefficients of cc together and the constant terms together.5.5c+5.4c=(5.5+5.4)c=10.9c5.5c + 5.4c = (5.5 + 5.4)c = 10.9c3.7+3.6=3.7+3.6=7.33.7 + 3.6 = 3.7 + 3.6 = 7.3
  2. Combine results: Combine the results from the previous step to get the final expression. 10.9c+7.310.9c + 7.3
