Question

3- 2x - \(\dfrac{1}{3}\) = 7x - \(\dfrac{1}{4}\)

giải chi tiết

Answer 1

Lời giải:

$3-2x-\frac{1}{3}=7x-\frac{1}{4}$

$3-\frac{1}{3}+\frac{1}{4}=2x+7x$

$\frac{35}{12}=9x$

$x=\frac{35}{108}$

Answer 2

\(3-2x-\dfrac{1}{3}=7x-\dfrac{1}{4}\)

\(\Leftrightarrow3-\dfrac{1}{3}+\dfrac{1}{4}=7x-2x\)

\(\Leftrightarrow5x=\dfrac{35}{12}\)

\(\Leftrightarrow x=\dfrac{7}{12}\)
