Chúc bạn học tốt.

😁😁😁

Ta có:

\(x:0,25+x.11=24\)

\(x.4+x.11=24\)

\(x\left(4+11\right)=24\)

\(x.15=24\)

\(x=1,6\)

\(x:0,25+x.11=24\)

<=> \(x:\frac{1}{4}+x.11=24\)

<=> \(x.4+x.11=24\)  <=> \(x.\left(4+11\right)=24\)

                                                 <=> \(15x=24\) <=>\(x=\frac{24}{15}\)

vậy \(x=\frac{24}{15}\)
