                     Lesson 1

 

                                                              Problem:               7x + 27  = 34                                                                                               

                                                                                                      

                                                             Solution                  Isolate the variable term on the left and numeric terms on right side.

                                                             Step 1:                      7x = 34 - 27

 

                           

                                                             Solution                  Transferring 27 from right side and subtracting it from 34,we get 7.

                                                             Step 2:                      7x = 34 27 = 7

                            

                                                            Solution                   Now dividing 7 by 7, we get 1.

                                                             Step 3:                       x = 7/7

 

                                                           Solution                    Answer is: x = 1

                                                            Step 4:                          

                                                           Complete      

 

                                                            Try two practice problems:                             

                                                            Determine the value of variables:

                               

                                                                                       A. 7q - 3 = 18       B. 5y - 7.1 = 3.4
