Inverse would be reverse of the steps done to x.
f:
multiplied by 2;
added 3.

inverse of f:
Starting with x,
subtract 3;
multiply by .

to find inverse first replace with
.......swap and
...........solve for

=>
compare:
what does to is: “multiply by , then add ”
what does to is:"divide by , then subtract divided by ”
