Question

TÌM X

\(\frac{2x+3}{10}-\frac{1}{10}=\frac{2x}{5}\)

Answer 1

\(\frac{2x}{10}+\frac{3}{10}-\frac{1}{10}=\frac{4x}{10}\)

\(-\frac{2x}{10}=-\frac{2}{10}\)

\(x=1\)

Answer 2

\(\frac{2x+3}{10}-\frac{1}{10}=\frac{2x}{5}\)

\(\frac{2x}{10}+\frac{3}{10}-\frac{1}{10}=\frac{4x}{10}\)

\(-\frac{2x}{10}=-\frac{2}{10}\)

\(\Rightarrow x=1\)

Answer 3

\(\frac{2x+3-1}{10}=\frac{2x}{5}\)

\(\frac{2x+2}{10}=\frac{2x}{5}\)

=> (2x + 2) . 2x = 10 . 5

=> 4.x² + 4x
