To find the inverse.
[tex]Solve\; x\cdot \:2-36=y \ \textgreater \ \mathrm{Add\:}36\mathrm{\:to\:both\:sides} \ \textgreater \ x\cdot \:2-36+36=y+36[/tex]
[tex]\mathrm{Simplify} \ \textgreater \ x\cdot \:2=y+36 \ \textgreater \ \mathrm{Divide\:both\:sides\:by\:}2 \ \textgreater \ \frac{x\cdot \:2}{2}=\frac{y}{2}+\frac{36}{2}[/tex]
Simplify again!
[tex]x=\frac{y+36}{2} \ \textgreater \ \mathrm{Subsititute\:}y=x \ \textgreater \ \frac{x+36}{2}[/tex]
[tex]Therefore\;\frac{x+36}{2}\;is\;the\;inverse![/tex]
Hope this helps!
