                      Example 2: Solve an equation

                      Reading time: 1min

                      Note that the solutions are a particular case of equivalent equations. But you can not decide if an equation is solved yet, or is not. Beware, you should not use this mode to ask for solutions to equations. For example, 
                      equivalent_eq_statement2.png 
                      with correct answer: 
                      equivalent_eq_correctanswer2.png

                      Then, the following answers will be accepted or rejected according to the table below:
