Question

Giúp mình vơi mình đang cần gấp.

Answer 1

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

\(\dfrac{1}{2}x=\dfrac{5}{10}+\dfrac{6}{10}\)

\(\dfrac{1}{2}x=\dfrac{11}{10}\\ x=\dfrac{22}{10}\)

\(x=\dfrac{11}{5}\)

Answer 2

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

\(\Rightarrow\dfrac{1}{2}x=\dfrac{11}{10}\)

\(\Rightarrow x=\dfrac{11}{5}\)

Answer 3

=> 0,5x = 1,1

=> x=2,2

 

Answer 4

Ta có: \(\dfrac{1}{2}x=\dfrac{1}{2}+\dfrac{3}{5}\)

nên \(x\cdot\dfrac{1}{2}=\dfrac{11}{10}\)

hay \(x=\dfrac{11}{5}\)
