Question

tim x biet: x + x/3=24

 

Answer 1

x+x/3 =24

x/1+x/3=24

3x+x/3=24

4x/3=24

4x=24.3

4x=72

x=72/4

x=18

Answer 2

\(+\frac{x}{3}=24\)

\(=>x+x.\frac{1}{3}\)\(=24\)

\(=>x.1+x.\frac{1}{3}=24\)

\(=>x.\left(1+\frac{1}{3}\right)=24\)

\(=>x.\frac{4}{3}\)\(=24\)

\(=>x=24:\frac{4}{3}\)

\(=>x=24.\frac{4}{3}\)

\(=>x=18\)
