Given :
It is given that
[tex]x=\frac{2}{5},y=\frac{5}{12}[/tex]
To find
[tex]-3y+x[/tex]
Explanation
In the given equation , substitute the value of x and y .
[tex]-3\times\frac{5}{12}+\frac{2}{5}=-\frac{5}{4}+\frac{2}{5}[/tex][tex]-\frac{5}{4}+\frac{2}{5}=\frac{-25+8}{20}=-\frac{17}{20}[/tex]
Answer
Hence the answer in simplest form is
[tex]-\frac{17}{20}[/tex]
