Question

tìm x \(0,2:1\frac{1}{5}=\frac{2}{3}:\left(6x+7\right)\)

Answer 1

0,2:1 1/5 = 2/3 : (6x + 7)

0,2:6/5 = 2/3 : (6x+7)

1/6 = 2/3 : (6x + 7 )

6x + 7 = 2/3 : 1/6

6x + 7 = 4

6x = 4 - 7 = - 3

x = -3 : 6

x = -1/2

Answer 2

2/3 : ( 6x + 7 ) = 1/6

Answer 3

\(0,2:1\frac{1}{5}=\frac{2}{3}:\left(6x+7\right)\)

\(\Leftrightarrow0,2\times\frac{5}{6}=\frac{2}{3}\times\frac{1}{6x+7}\)

\(\Leftrightarrow\frac{1}{6}:\frac{2}{3}=\frac{1}{6x+7}\)

\(\Leftrightarrow\frac{1}{4}=\frac{1}{6x+7}\)

\(\Leftrightarrow6x+7=4\)

\(\Leftrightarrow6x=-3\)

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