Question

Tìm x :

x : 8 + x .8 - 56,78 =6,11 . 2

 

Answer 1

x : 8 + x . 8 - 56,78 = 6,11 . 2

x . 1/8 + x . 8 - 56,78 = 12,22

x . ( 1/8 + 8 ) - 56,78 = 12,22

x . 8,125 - 56,78 = 12,22

x . 8,125 = 12,22 + 56,78 = 69

x            = 69 : 8,125 = 8.49230769231

Answer 2

x : 8 + x . 8 ‐ 56,78 = 6,11 . 2

x . 1/8 + x . 8 ‐ 56,78 = 12,22

x . ﴾ 1/8 + 8 ﴿ ‐ 56,78 = 12,22

x . 8,125 ‐ 56,78 = 12,22

x . 8,125 = 12,22 + 56,78 = 69

x = 69 : 8,125 = 8.49230769231

Answer 3

x : 8 + x . 8 ‐ 56,78 = 6,11 . 2

x . 1/8 + x . 8 ‐ 56,78 = 12,22

x . ﴾ 1/8 + 8 ﴿ ‐ 56,78 = 12,22

x . 8,125 ‐ 56,78 = 12,22

x . 8,125 = 12,22 + 56,78 = 69

x = 69 : 8,125 = 8.49230769231
