Question

\(\dfrac{6}{13}\)- 0,5 . x = \(\dfrac{-3}{2}\)

giúp mình câu này với ạ mình cần gấp ạ

Answer 1

\(\dfrac{6}{13}-0,5.x=\dfrac{-3}{2}\)
\(\dfrac{1}{2}x=\dfrac{6}{13}-\dfrac{-3}{2}\)
\(\dfrac{1}{2}x=\dfrac{12}{26}+\dfrac{39}{26}\)
\(\dfrac{1}{2}x=\dfrac{51}{26}\)
\(x=\dfrac{51}{26}:\dfrac{1}{2}\)
\(x=\dfrac{51}{26}.2\)
\(x=\dfrac{51}{13}\)
Vậy \(x=\dfrac{51}{13}\)

Answer 2

\(\dfrac{6}{13}-0,5x=-\dfrac{3}{2}\)

\(0,5x=\dfrac{6}{13}-\left(-\dfrac{3}{2}\right)\)

\(0,5x=\dfrac{51}{26}\)

\(x=\dfrac{51}{26}:0,5\)

\(x=\dfrac{51}{13}\)
