Question

\(1-\left(5\frac{4}{9}+x-7\frac{7}{18}\right)\div15-\frac{3}{4}=0\)

Answer 1

khỏi chép lại đề nha

\(1-\left(\frac{49}{9}+x-\frac{133}{18}\right):15=0+\frac{3}{4}\)

\(1-\left(\frac{49}{9}+x-\frac{133}{18}\right):15=\frac{3}{4}\)

\(1-\left(\frac{49}{9}+x-\frac{133}{18}\right)=\frac{3}{4}.15\)

\(1-\left(\frac{49}{9}+x-\frac{133}{18}\right)=\frac{45}{4}\)

\(\frac{49}{9}+x-\frac{133}{18}=1-\frac{45}{4}\)

\(\frac{49}{9}+x-\frac{133}{18}=\frac{-41}{4}\)

\(\frac{49}{9}+x=\frac{-41}{4}+\frac{133}{18}\)

\(\frac{49}{9}+x=\frac{-103}{36}\)

\(x=\frac{-103}{3}-\frac{49}{9}\)

\(x=\frac{-299}{36}\)
