Answer 1

giup minh nhe

Answer 2

\(\frac{1+2y}{18}=\frac{1+4y}{24}\Rightarrow\left(1+2y\right).24=\left(1+4y\right).18\)

\(\Rightarrow24+48y=18+72y\)

\(\Rightarrow24-18=-48y+72y\Rightarrow6=24y\Rightarrow y=\frac{24}{6}=4\)

\(\Rightarrow\frac{1+2y}{18}=\frac{1+8}{18}=\frac{9}{18}=\frac{1}{2}\)

\(\frac{1+2y}{18}=\frac{1+6y}{6x}=\frac{1+24}{6x}=\frac{25}{6x}=\frac{1}{2}\Rightarrow6x=30\Rightarrow x=5\)

vậy x=5,y=4

Answer 3

eeeeeeeeeiiiiiiiiiiii 

\(6=24y\Rightarrow y=\frac{6}{24}=\frac{1}{4}thayvaoroitinh\)
