Given the expression:
[tex]x-4y[/tex]Let's evaluate the expression when x = -7/15 and y = 2/5
To evaluate the expression, substitute the values for the variables into the expression:
[tex]\begin{gathered} -\frac{7}{15}-(4*\frac{2}{5}) \\ \\ -\frac{7}{15}-\frac{8}{5} \\ \\ \frac{1(-7)-3(8)}{15} \\ \\ =\frac{-7-24}{15} \\ \\ \end{gathered}[/tex]Solving further:
[tex]\begin{gathered} \frac{}{}\frac{-31}{15} \\ \\ =-2\frac{1}{15} \end{gathered}[/tex]ANSWER:
[tex]-2\frac{1}{15}[/tex]
