89
57
(5x-6)
                                             
                                          
                                          
                                        
											 
											Answer:
89+57 = 146
146+(5x-6) = 180
146-146+(5x-6) = 180-146
5x-6 = 34
5x-6+6 = 34+6
5x = 40
5x/5 = 40/5
x = 8
