Question

Giúp mình giải bài này nhé , mình đang rất gấp.

 

Tìm x biết : 1 - ( 5 4/9 + x - 7 7/18 ) : 15 3/7 = 0

 

Answer 1

=>\(\left(\frac{49}{9}+x-\frac{133}{18}\right):\frac{108}{7}=1\)

=>\(\frac{49}{9}+x-\frac{133}{18}=\frac{108}{7}\)

=>\(\frac{49}{9}+x=\frac{108}{7}+\frac{133}{18}\)

=>\(\frac{49}{9}+x=\frac{2875}{126}\)

=>\(x=\frac{2975}{126}-\frac{49}{9}\)

=>\(x=\frac{2189}{126}\)

Answer 2

2189/162
