Question

X - 4   5/6 = 2  1/6 + 5/6 ( hỗn nha nha a   b/a)

X + 2/3 = 2  1/2 ( hỗn số )

8,75 x X + 1,25 xX =26,3

5  4/5 + X - 7  7/18 = 15   3/4 ( hỗn số )

Answer 1

\(x+\frac{2}{3}=2\frac{1}{2}\)

\(x+\frac{2}{3}=\frac{5}{2}\)

\(x=\frac{5}{2}-\frac{2}{3}\)

\(x=\frac{11}{6}\)

\(8,75.x+1,25.x=26,3\)

\(x.\left(8,75+1,25\right)=26,3\)

\(x.10=26,3\)

\(x=26,3\div10\)

\(x=2,63\)

Answer 2

\(x-4\frac{5}{6}=2\frac{1}{6}+\frac{5}{6}\)

\(x-\frac{29}{6}=3\)

\(x=\frac{47}{6}\)

Answer 3

\(5\frac{4}{5}+x-7\frac{7}{18}=15\frac{3}{4}\)

\(\frac{29}{5}+x-\frac{133}{18}=\frac{63}{4}\)

\(\frac{29}{5}+x=\frac{63}{4}+\frac{133}{18}\)

\(\frac{29}{5}+x=\frac{259}{8}\)

\(x=\frac{259}{8}-\frac{29}{5}\)

\(x=\frac{1063}{40}\)

Answer 4

X - \(4\frac{5}{6}\)= \(2\frac{1}{6}\)+ \(\frac{5}{6}\)

 X - \(\frac{29}{6}\)= \(\frac{13}{6}\)+ \(\frac{5}{6}\) 

X               = \(\frac{13}{6}+\frac{5}{6}+\frac{29}{6}\)

X               =\(\frac{47}{6}\)

Ủng hộ nha! :)   

Answer 5

\(x-\frac{29}{6}=\frac{13}{6}+\frac{5}{6}\)

\(x-\frac{29}{6}=3\)

\(x=3+\frac{29}{6}=\frac{47}{6}\)

\(X+\frac{2}{3}=\frac{5}{2}\)

\(X=\frac{5}{2}-\frac{2}{3}\)

X = 11/6

X x ( 8,75 +1,25 ) = 26,3

X x  10               = 26 ,3

X                       = 26,3 : 10

X                       = 2,63

\(\frac{29}{5}+x-\frac{133}{18}=\frac{63}{4}\)

\(\frac{29}{5}+x=\frac{63}{4}+\frac{133}{18}=\frac{833}{36}\)

            \(x=\frac{833}{36}-\frac{29}{5}=\frac{3121}{180}\)
