Question

X + 3,5 - \(\frac{4}{7}=\frac{3}{2}-5\frac{1}{8}\)

Answer 1

\(x+3,5-\frac{4}{7}=\frac{3}{2}-5\frac{1}{8}\)

=> \(x+\frac{35}{10}-\frac{4}{7}=\frac{3}{2}-\frac{41}{8}\)

=> \(x+\frac{7}{2}-\frac{4}{7}=\frac{12}{8}-\frac{41}{8}\)

=> \(x+\frac{7}{2}-\frac{4}{7}=-\frac{29}{8}\)

=> \(x+\frac{7}{2}=-\frac{29}{8}+\frac{4}{7}=-\frac{171}{56}\)

=> \(x=-\frac{171}{56}-\frac{7}{2}=-\frac{367}{56}\)

Answer 2

Trả lời:

\(x+3,5-\frac{4}{7}=\frac{3}{2}-5\frac{1}{8}\)

\(\Leftrightarrow x+\frac{7}{2}-\frac{4}{7}=\frac{3}{2}-\frac{41}{8}\)

\(\Leftrightarrow x+\frac{7}{2}-\frac{4}{7}=\frac{-29}{8}\)

\(\Leftrightarrow x+\frac{7}{2}=\frac{-171}{56}\)

\(\Leftrightarrow x=\frac{-367}{56}\)

Vậy \(x=\frac{-367}{56}\)

Answer 3

\(x+3.5-\frac{4}{7}=\frac{3}{2}-5\frac{1}{8}\)

\(x+\frac{7}{2}-\frac{4}{7}=\frac{3}{2}-\frac{41}{8}\)

\(x+\frac{41}{14}=-\frac{29}{8}\)

\(x=-\frac{367}{56}\)

Answer 4

X + \(\frac{7}{2}\)- \(\frac{4}{7}\)=\(\frac{3}{2}\)- \(\frac{41}{8}\)

X + \(\frac{7}{2}\)- \(\frac{4}{7}\)=   \(\frac{-29}{8}\)

X + \(\frac{7}{2}\)          =   \(\frac{-29}{8}\)+ \(\frac{4}{7}\)

X + \(\frac{7}{2}\)          = \(\frac{-171}{56}\)

X                       = \(\frac{-171}{56}\)- \(\frac{7}{2}\)

X                       =\(\frac{-367}{56}\)

Answer 5

x+3,5-4/7=3/2-41/8

x+3,5-4/7=-29/8

x+3,5=-29/8+4/7

x+3,5=-171/56

x=-171/56-3,5

x=-171/56-7/2

x=-367/56

vậy x=-367/56
