Ta có: \(x+\frac{x}{3}=96-12.5\)
\(\Rightarrow\frac{2x}{3}=96-60\)
\(\Rightarrow2x:3=36\)
\(\Rightarrow2x=36.3=108\)
\(\Rightarrow x=108:2=54\)
Vậy x = 54
\(x+\frac{x}{3}=96-60=36\)
\(x+x\times\frac{1}{3}=36\)
\(x\times\frac{4}{3}=36\)
\(x=36:\frac{4}{3}=27\)
\(x+\frac{x}{3}=96-60\)
\(\Leftrightarrow x.1+x.\frac{1}{3}=36\)\(\Leftrightarrow x.\left(1+\frac{1}{3}\right)=36\)
\(\Leftrightarrow x.\frac{4}{3}=36\Rightarrow x=36:\frac{4}{3}\)\(\Rightarrow x=27\)
x + x/3 = 96 - 60
x + x/3 = 36
=> x + x : 3 = 36
=> x : 3 = 36 - x
=> x = ( 36 - x ) . 3
=> x = 36.3 - x.3
=> x = 108 - x.3
