HELP ME

4/5 - 2x = 2/5 + 3x

Answer 1

\(\frac{4}{5}-2x=\frac{2}{5}+3x\)

\(\frac{4}{5}-\frac{2}{5}=2x+3x\)

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

\(x=\frac{2}{25}\)

Answer 2

Ta có :\(\frac{4}{5}-2x=\frac{2}{5}+3x\)

\(\Leftrightarrow\) \(\frac{4}{5}-\frac{2}{5}=3.x+2.x\)

\(\Leftrightarrow\)\(\frac{2}{5}=5.x\)

\(\Leftrightarrow x=\frac{2}{5}:5\)

\(\Leftrightarrow x=\frac{2}{25}\)

~~~ AI NGANG QUA CHO CHÁU XIN 1 L~I~K~E~~~

Answer 3

Ta có:

\(\frac{4}{5}-2x=\frac{2}{5}+3x\)

=>\(\frac{4}{5}-2x-\frac{2}{5}=3x\)

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

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

=>\(\frac{2}{5}=5x\)

=>\(x=\frac{2}{5}:5\)

=>\(x=\frac{2}{25}\)

Vậy  \(x=\frac{2}{25}\)
