fx=2\sin(2,5+0,5\left(-\frac{x}{0,5}\right))
Use the distributive property to multiply 0,5 by 5-\frac{x}{0,5}.
fx=2\sin(2,5-0,5\times \frac{x}{0,5})
Multiply 0,5 and -1 to get -0,5.
xf=2\sin(2,5-x)
The equation is in standard form.
\frac{xf}{x}=\frac{2\sin(2,5-x)}{x}
Divide both sides by x.
f=\frac{2\sin(2,5-x)}{x}
Dividing by x undoes the multiplication by x.
