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.
\(5\frac{4}{7}\): {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
