x – x + $\frac{1}{3}$ = 2x + $\frac{1}{5}$ x – x – 2x = $\frac{1}{5}$ -$\frac{1}{3}$ -2x = $\frac{-2}{15}$ x = $\frac{1}{15}$ Trả lời
x-x+1/3=2x+1/5
(=) 1/3 = 2x + 1/5
(=) 2x = 2/15
(=) x=1/15
x – x + $\frac{1}{3}$ = 2x + $\frac{1}{5}$
x – x – 2x = $\frac{1}{5}$ -$\frac{1}{3}$
-2x = $\frac{-2}{15}$
x = $\frac{1}{15}$
