Question

10целых 10/17-(х+2/17)=8целых9/17

Answer 1

х +2 /17= 10.10/17-8.9/17

х+2/17= 2 .1/17

х=2.1/17-2/17

х=1.16/17

Answer 2

10 10/17 - ( х + 2/17) = 8 9/17

 

 ( х +2/17) = 10 10/17 - 8 9/17 = 180/17 - 145/17 = 35/17 = 2 1/17

 

 х = 2/17 + 35/17 = 37/17       х =  37/17 = 2 3/17

 

Проверяем:  10 10/17 - (  2 3/17 - 2/17) = 10 10/17 - 2 1/17 = 8 9/17
