\(x+x\div5+x\div2=34\)
\(\Leftrightarrow x+x.\frac{1}{5}+x.\frac{1}{2}=34\)
\(\Leftrightarrow x\left(1+\frac{1}{5}+\frac{1}{2}\right)=34\)
ez rồi, tự giải tiếp
x + x : 5 + x: 2 = 34
x + x: ( 5 + 2 ) = 34
x + x : 7 = 34
x + x = 34 * 7
2x = 238
x = 238 : 2
x = 119
=>\(x\times1+x\times\frac{1}{5}+x\times\frac{1}{2}=34\)
=>\(x\times\left(1+\frac{1}{5}+\frac{1}{2}\right)=34\)
=>\(x\times1\frac{7}{10}=34\)
=>\(x=20\)
\(x+\frac{x}{5}+\frac{x}{2}=34\)
\(\Rightarrow x.\left(1+\frac{1}{5}+\frac{1}{2}\right)=34\)
\(\Rightarrow x.\frac{10+2+5}{10}=34\)
\(\Rightarrow x.\frac{17}{10}=34\)
\(\Rightarrow x=34:\frac{17}{10}=34.\frac{10}{17}\)
\(\Rightarrow x=20\)
\(x+\frac{x}{5}+\frac{x}{2}=34\)
\(\Leftrightarrow x\times\left(1+\frac{1}{5}+\frac{1}{2}\right)=34\)
\(\Leftrightarrow x\times\frac{17}{10}=34\)
\(\Leftrightarrow x=34\div\frac{17}{10}\)
\(\Leftrightarrow x=20\)
