Question

[Nguyễn Tiến Long]

\(x\):2+\(x\)+\(x\):3+\(x\):4=25

Answer 1

[Akai Haruma]

Lời giải:
$x:2+x+x:3+x:4=25$

$x\times \frac{1}{2}+x\times 1+x\times \frac{1}{3}+x\times \frac{1}{4}=25$

$x\times (\frac{1}{2}+1+\frac{1}{3}+\frac{1}{4})=25$

$x\times \frac{25}{12}=25$

$x=25: \frac{25}{12}=12$

Answer 2

[Nguyễn Thị Hải Vân]

x: 2+x+x:3+x:4=25

x:2+x:1+x:3+x:4=25

X:(2+1+3+4)=25

X:10=25

x=25:10

x=2,5
