7/2x5? just a guess. I'm not sure.

well I know, but 7 is the opposite of 7. There aren't any 5s in it either. That looks like a +5 up there.

I don't think it necessarily wants the opposite of everything

switch x and y and solve for y for the inverse of a function. \[x = \frac{ 2y+5 }{ 7}\]

\[y = \frac{2x + 5}{7}\] To get the inverse, solve for x, then swap x and y \[y = \frac{2x + 5}{7}\] \[7y  5 = 2x\] \[x = \frac{7y  5}{2}\] So the inverse function is \[f^{1}(x) = \frac{7x  5}{2}\]
