`x:0,25+x xx11=39`

`x xx4 + x xx11=39`

`x xx(4+11)=39`

`x xx15=39`

`x =13/5`

X:0,25+X x 11 =39

=> X x 4 + X x 11 =39

=> X x( 4+11) =39

=> X x 15 =39

=>         X =39 :15

=>         X=2,6

= X x 4 + X x 11 = 39 

= X x 15 = 39

= 39 / 15 = 2,6

⇒ X x 4 + X x 11 = 24

⇒ X x ( 4+11) = 24

⇒ X x 15 = 24

⇒ X  = 24 : 15 = 1,6

X: 0,25 + X x 11 = 24
<=> X x 4 + X x 11= 24
<=> X x (4+11)= 24
<=> X x 15= 24
=> X= 24/15

\(x:0,25+x\times11=24\)

\(\Rightarrow x\times4+x\times11=24\)

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

\(\Rightarrow x\times15=24\)

\(\Rightarrow x=\dfrac{8}{5}\)

Vậy: \(x=\dfrac{8}{5}\)

(: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

      \(x:0,25+x\cdot11=24\)

<=> \(x.\frac{1}{4}+x.11=24\)

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

<=> \(x.\frac{45}{4}=24\)

<=> \(x=\frac{32}{15}\)

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

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

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

x / 0,25 + x * 11 = 24

x * 4 + x * 11 = 24

x * 15 = 24

x = 24/15

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

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

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

\(x.\frac{54}{4}=24\) 

         \(x=24:\frac{54}{4}\)

          \(x=24.\frac{4}{45}\)

          x=\(\frac{96}{45}\)

vạy x=\(\frac{96}{45}\)

 \(x : 0,25 + x * 11 = 24\)

\(x : 1/4 + x * 11= 24\)

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

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

\(x*15=24\)

\(x=24:15\)

\(x = 1,6\)
