Question

12 7/23 -(6 18/23 -t) = 3 21|23 + 5 19|23 как решить?

Answer 1

12 7/23 -(6 18/23 -t) = 3 21/23 + 5 19/23      

    12 7/23 -(6 18/23 -t) = 8 40/23    

       6 18/23 -t = 12 7/23-8 40/23         

       6 18/23 -t = 10 53/23-8 40/23     

   6 18/23 -t = 2 13/23

t=6 18/23 - 2 13/23

t=4 5/23
