Question

Tìm y

y x \(\frac{15}{2}\)- \(\frac{1}{3}\)x (\(\frac{1}{4}\)+y) =96\(\frac{2}{3}\)

giúp với

Answer 1

y= 13,5

Answer 2

Trả lời:

\(y\times\frac{15}{2}-\frac{1}{3}\times\left(\frac{1}{4}+y\right)=96\frac{2}{3}\)

\(\Leftrightarrow y\times\frac{15}{2}-\frac{1}{12}-\frac{1}{3}\times y=\frac{290}{3}\)

\(\Leftrightarrow y\times\left(\frac{15}{2}-\frac{1}{3}\right)=\frac{387}{4}\)

\(\Leftrightarrow y\times\frac{43}{6}=\frac{387}{4}\)

\(\Leftrightarrow y=\frac{27}{2}\)

Vậy \(y=\frac{27}{2}\)

Answer 3

y.15/2-1/3.(1/4+y)=96 2/3

y.15/2-1/12-1/3y=290/3

y.15/2-1/3y=290/3+1/12

y.15/2-1/3y=1161/12

y.(15/2-1/3)=1161/12

y.43/6=1161/12

->y=1161/12:43/6

->y=27/2

->y=13,5

Answer 4

mik tính lại rồi, vẫn ra 13,5
