You probably will never find a simpler

problem in your algebra textbook, lol.  

 

                                                    a + ab  =    250   

                                                    a – ab  =  –240  

Just add the two together.  

                                                  2a          =      10    

Divide both sides by 2.  

                                                            a  =  5    

The problem didn't ask for b.
