Question

50%x+ 2/3x = x+4

 

Answer 1

\(50\%x+\frac{2}{3}x=x+4\)=> \(\frac{1}{2}x+\frac{2}{3}x-x=4\)=> \(\frac{1}{6}x=4\)=> \(x=24\)

Answer 2

\(\Rightarrow\frac{1}{2}x+\frac{2}{3}x=x+4\)

\(\Rightarrow\frac{7}{6}x-x=4\)

\(\Rightarrow\frac{1}{6}x=4\)

\(\Rightarrow x=4:\frac{1}{6}\)

\(\Rightarrow x=4\cdot6\)

\(\Rightarrow x=24\)

Answer 3

\(50\%x=\frac{1}{2}x\)

Ta có : 

\(\frac{1}{2}x+\frac{2}{3}x=x+4\)

\(\frac{1}{2}x+\frac{2}{3}x-x=4\)

\(=>\frac{1}{6}x=4\)

\(x=\frac{4}{\frac{1}{6}}\)

\(x=24\)
