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 = 1,6
Vậy X = 1,6
\(x:0,25+x\times11=24\\ \Rightarrow x:\dfrac{1}{4}+x\times11=24\\ \Rightarrow x\times4+x\times11=24\\ \Rightarrow x\times\left(4+11\right)=24\\ \Rightarrow x\times15=24\\ \Rightarrow x=\dfrac{24}{15}\\ \Rightarrow x=\dfrac{8}{5}\)
x : 0,25 + x . 11 =24
=> x :1/4 + x . 11 = 24
=> x.(4 + 11) =24
=> x . 15 = 24
=> x = 24 : 15
=> x = 8/5=1.6
