Question

Малю помогите с решением номер 1086

Answer 1

(143,71-2,71)у-41у=461,6-1,6     

141у-41у=460

 100у=460

   у=4,6

  (143,71+4,29)у-48у=384,7-4,7          
             
   148у-48у=380

    100у=380

     у=3,8


34(х+1,2)-1,2=60  
                     
34х+40,8-1,2=60    
  
34х=60-40,8+1,2    
                    
34х=20,4   
                                
х=0,6     

                                      
295,1/(х-3)-12,7=0,3  
                                                      
 295,1/(х-3)=0,3+12,7  
                                                   
 295,1/(х-3)=13   
                                                  
13(х-3)=295,1

 13х-39=295,1

13х=295,1+39

13х=334,1

   х=25,7
