Question

Tìm \(x\): biết

14 x \(x\) + \(x\) x 26 = 25

help gấp ạ

Answer 1

\(14\times x+x\times26=25\\ \Rightarrow x\times\left(14+26\right)=25\\ \Rightarrow x\times40=25\\ \Rightarrow x=25:40\\ \Rightarrow x=\dfrac{5}{8}\)

Vậy \(x=\dfrac{5}{8}\)

Answer 2

cứu mik đi mà :(

Answer 3

14*x+x*26= 25

x*\(\left(14+26\right)\)= 25

x*40= 25

x= 25/40

x= 0,625
