Question

Tìm x biết x - \(\dfrac{3}{5}\) = \(\dfrac{2}{7}\) + \(\dfrac{1}{6}\)

Answer 1

\(x-\dfrac{3}{5}=\dfrac{2}{7}+\dfrac{1}{6}\)

\(\Leftrightarrow x-\dfrac{3}{5}=\dfrac{19}{42}\)

\(\Leftrightarrow x=\dfrac{19}{42}+\dfrac{3}{5}\)

\(\Leftrightarrow x=\dfrac{221}{210}\)

Answer 2

=>x-3/5=12/42+7/42=19/42

=>x=19/42+3/5=95/210+126/210=221/210

Answer 3

x-3/5=2/7+1/6

x-3/5=12/42+7/42

x-3/5=19/42

x=19/42+3/5

x=95/210 + 126/210

x=221/210
