Yes.

x=5y+12
anonymous

\[x = 5y +12\]
anonymous

Solve for x.
anonymous
  • anonymous
lol
anonymous
  • anonymous
x-12=5y
anonymous
  • anonymous
(x-12)/5=y
anonymous
  • anonymous
\[5y = x -12\]
anonymous
  • anonymous
\[y = \frac{ x-12 }{ 5 }\rightarrow f ^{-1}(x)=\frac{ x }{ 5 }-\frac{ 12 }{5 }\]
