Question

2/3+1/3:x=3/5

Answer 1

2/3+1/3:x=3/5

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

\(\frac{1}{3x}=-\frac{1}{15}\)

-1(3x)=15

-3x=15

x=-5

Answer 2

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

\(\Rightarrow\frac{1}{3}:x=\frac{3}{5}-\frac{2}{3}\)

\(\Rightarrow\frac{1}{3}:x=-\frac{1}{15}\)

\(\Rightarrow x=\frac{1}{3}:\left(-\frac{1}{15}\right)\)

\(\Rightarrow x=-5\)

Vậy x=-5

Answer 3

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

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

\(\frac{1}{3}:x=-\frac{1}{15}\)

\(x=\frac{1}{3}:-\frac{1}{15}\)

\(x=-5\)
