Question

720:(41-2x-5)=23,5

Tìm x

Answer 1

\(720:\left(41-2x-5\right)=23,5\)

<=> \(41-2x-5=\frac{1440}{47}\)

<=> \(x=2,680851064\)

Answer 2

\(720:\left(41-2x-5\right)=23,5\)

\(\Leftrightarrow720:36-720:2x=23,5\)

\(\Leftrightarrow20-720:2x=23,5\)

\(\Leftrightarrow-720:2x=23,5-20\)

\(\Leftrightarrow-720:2x=3,5\)

\(\Leftrightarrow2x=\frac{-1440}{7}\)

\(\Leftrightarrow x=\frac{-720}{7}\)

Answer 3

720 : ( 41 - 2x - 5 ) = 23.5

41 - 2x - 5 = 720 : 23.5

41 - 2x - 5 = 1440/47

36 - 2x = 1440/47

2x = 36 - 1440/47

2x = 252/47

x = 252/47 : 2

x = 126/47

Answer 4

126/47 nha bn
