Question

x cộng 3 phần 5 bằng 1 phần 3

 

Answer 1

x+3/5=1/3

->x=1/3-3/5

->x=-4/15

Answer 2

x+\(\dfrac{3}{5}=\dfrac{1}{3}\)

x       =\(\dfrac{1}{3}-\dfrac{3}{5}\)

x       =\(\dfrac{-4}{15}\)

Answer 3

\(x+\dfrac{3}{5}=\dfrac{1}{3}\)

\(\Leftrightarrow x=\dfrac{1}{3}-\dfrac{3}{5}\)

\(\Leftrightarrow x=\dfrac{5}{15}-\dfrac{9}{15}\)

\(\Leftrightarrow x=\dfrac{-3}{15}=\dfrac{-1}{5}\)
