Question

[Nguyễn Hồng Như]

tìm y!:

\(3\frac{1}{3}y+16\frac{3}{4}=13,25\)

Answer 1

[Arima Kousei]

\(3\frac{1}{3}y+16\frac{3}{4}=13,25\)

\(\Rightarrow\frac{10}{3}y+\frac{67}{4}=13\frac{1}{4}\)

\(\Rightarrow\frac{10}{3}y+\frac{67}{4}=\frac{53}{4}\)

\(\Rightarrow\frac{10}{3}y=\frac{53}{4}-\frac{67}{4}\)

\(\Rightarrow\frac{10}{3}y=\frac{-14}{4}\)

\(\Rightarrow y=-\frac{14}{4}:\frac{10}{3}\)

\(\Rightarrow y=-\frac{14}{4}.\frac{3}{10}\)

\(\Rightarrow y=\frac{-21}{20}\)

Chúc bạn học tốt !!! 

Answer 2

[tiến dũng]

10/3 .y+ 67/4=1325/100

10/3.y=-7/2

y=-7/60
