Question

x : 0,25 + x * 11 =24

Answer 1

(:0,25=*4)

Ta có:x*4+x*11=24

x*(11+4)=24

x*15=24

x=24:15

x=1,6

K nhé

Answer 2

      \(x:0,25+x\cdot11=24\)

<=> \(x.\frac{1}{4}+x.11=24\)

<=> \(x.\left(\frac{1}{4}+11\right)=24\)

<=> \(x.\frac{45}{4}=24\)

<=> \(x=\frac{32}{15}\)

Answer 3

\(0,25=\frac{1}{4}\)

\(\Rightarrow x:\frac{1}{4}+x.11=24\) \(\Rightarrow x.4+x.11=24\)

\(\Rightarrow x.\left(4+11\right)=24\)\(\Rightarrow x.15=24\) \(\Rightarrow x=\frac{24}{15}\)
