Question

12/7 : x + 2/3 = 6/5 đây là bài x

Answer 1

12/7:x=6/5-2/3

12/7:x=8/15

       x=12/7:8/15

       x=45/14

Answer 2

\(\frac{12}{7}\div x+\frac{2}{3}=\frac{6}{5}\)

\(\frac{12}{7}\div x=\frac{6}{5}-\frac{2}{3}\)

\(\frac{12}{7}\div x=\frac{18}{15}-\frac{10}{15}\)

\(\frac{12}{7}\div x=\frac{8}{15}\)

\(x=\frac{12}{7}\div\frac{8}{15}\)

\(x=\frac{12}{7}\times\frac{15}{8}\)

\(x=\frac{45}{14}\)

Answer 3

\(\frac{12}{7}:x+\frac{2}{3}=\frac{6}{5}\)

\(\frac{12}{7}:x=\frac{6}{5}-\frac{2}{3}\)

\(\frac{12}{7}:x=\frac{8}{15}\)

\(\frac{12}{7}:\frac{8}{15}\)

\(3\frac{3}{14}\)

k mk nhé , 

Answer 4

\(\frac{12}{7}:x+\frac{2}{3}=\frac{6}{5}\)

\(\frac{12}{7}:x=\frac{6}{5}-\frac{2}{3}\)

\(\frac{12}{7}:x=\frac{8}{15}\)

\(x=\frac{12}{7}:\frac{8}{15}\)

\(x=\frac{12}{7}x\frac{15}{8}\)

\(x=\frac{45}{14}\)

Answer 5

\(\frac{12}{7}\): x + \(\frac{2}{3}\)=\(\frac{6}{5}\)

\(\frac{12}{7}\): x            =\(\frac{6}{5}\)- \(\frac{2}{3}\)

\(\frac{12}{7}\): x            =\(\frac{8}{15}\)

            x             =\(\frac{12}{7}\):\(\frac{8}{15}\)

            x             =\(\frac{45}{14}\)
