\(115-20:5x=95\)
\(\Rightarrow115-4x=95\)
\(\Rightarrow4x=115-95\)
\(\Rightarrow4x=20\)
\(\Rightarrow x=5\)
\(115-20\div5.x=95\)
\(\Rightarrow115-4x=95\)
\(\Rightarrow115-95=4x\)
\(\Rightarrow4x=20\Rightarrow x=\frac{20}{4}=5\)
Vậy\(x=5\)
\(115-20:5x=95\)
\(=>115-4x=95\)
\(4x=115-95\)
\(4x=20\)
\(=>x=5\)
