Question

Tìm x, biết:

\(-\frac{15}{12}.x+\frac{3}{7}=\frac{6}{5}.x-\frac{1}{2}\)

Answer 1

\(\frac{130}{343}\)

Answer 2

130/343

**** mọi người thanks nhìu

Answer 3

130/343 nha

Answer 4

\(\frac{130}{343}\)

Answer 5

\(-\frac{15}{12}x+\frac{3}{7}=\frac{6}{5}x-\frac{1}{2}\)

\(\Leftrightarrow-\frac{6}{5}x-\frac{15}{12}x=-\frac{1}{2}-\frac{3}{7}\)

\(\Leftrightarrow-\frac{123}{60}x=-\frac{13}{14}\)

\(\Leftrightarrow x=-\frac{13}{14}:\frac{-123}{60}\)

\(\Leftrightarrow x=\frac{130}{343}\)

Answer 6

130/343

Answer 7

\(-\frac{15}{12}x+\frac{3}{7}=\frac{6}{5}x-\frac{1}{2}\)

\(\Rightarrow-\frac{15}{12}x-\frac{6}{5}x=-\frac{1}{2}-\frac{3}{7}\)

\(\Rightarrow x(-\frac{15}{12}-\frac{6}{5})=\frac{-13}{14}\)

\(\Rightarrow\frac{-49}{20}x=\frac{-13}{14}\)

\(\Rightarrow x=\frac{-13}{14}\div\frac{-49}{20}\)

\(\Rightarrow x=\frac{130}{343}\)

Answer 8

\(\frac{130}{343}\)
