Question

determine a solução da equação (8,3737...) x -5,420202020... = 100

Answer 1

8,3737...x - 5,42020... = 100
x = (100 + 5,42020...)/8,3737...
x = 12,59

Answer 2

(8,3737...) x -5,420202020... = 100

(837-8)x  - (5420-5) = 100
  99              999

829x - 5415 = 100
   99       999

92019x - 59565 = 1098900 ==> 92019x = 59565 + 1098900

92019x = 1158465 ==> x =  1158465/92019





999,99  3
333,33  3
111, 11  11
 111,  1  111

3.3.11.111 = 10989
