tìm x biết:
\(5\frac{4}{7}:\left\{x:1,3+8,4.\frac{6}{7}.\left[6-\frac{\left(2,3+5:6,25\right).7}{8.0,0125+6,9}\right]\right\}=1\frac{1}{14}\)
Tìm x, biết:
a) 2 1 3 + 3 1 2 : x + 3 1 7 + 7 1 2 = 1 69 86
b) 7 + 0 , 004. x : 0 , 9 : 24 , 7 − 12 , 3 = 77 , 7
c) 6 3 7 − 0 , 75 x − 2 0 , 35 .2 , 8 + 1 , 75 : 0 , 05 = 235
d) 5 4 7 : x : 1 , 3 + 8 , 4. 6 7 . 6 − 2 , 3 + 5 : 6 , 25 .7 8.0 , 0125 + 6 , 9 = 1 1 14
Mọi người giúp mình bài này với :

Hello everyone, my name is James. I'm from America. I'm in grade 7. I'm not good at math so can you help me to do this math question?
Find x
\(5\frac{4}{7}:\left\{x:1,3+8,4.\frac{6}{7}.\left[6-\frac{\left(2,3+5:6,25\right).7}{8.0,0125+6,9}\right]\right\}=1\frac{1}{14}\)
I hope you will help me.
tính giá trị biểu thức
a)\(1\frac{13}{15}.0,75-\left(\frac{104}{195}+25\%\right).\frac{24}{47}-3\frac{12}{13}:3\)
b)\(6-\frac{\left(2,3+5:6,25\right).7}{8.0,0125+6,9}\)
c)\(\)
\(5\frac{4}{7}\): {x : 1.3 + 8,4 .\(\frac{6}{7}\)[6- \(\frac{\left(2,3+5.6,25\right).7}{8.0,0125+6,9}\)]} = 11
giải giúp mk với thanks các bạn
tính giá trị biểu thức
a) \(\left|111-324\right|+\left|-2-415\right|+\left|354-123\right|\)
b) \(\left|-2^3+5^2-35\right|-\left|3^4-2^5-12^2\right|\)
c) \(1\frac{13}{15}.0,75-\left(\frac{104}{195}+25\%\right).\frac{24}{47}-3\frac{12}{13}:3\)
d) \(\left(2\frac{1}{3}-1\frac{1}{9}\right):4-\frac{3}{4}\)
e)\(6-\frac{\left(2,3+5:6,25\right).7}{8.0,0125+6,9}\)
g)\(45\frac{10}{63}-44\frac{25}{84}\)
