It's D.
.
Why?
.
Ok, your variable is x.
.
x stands for WHAT( the VALUE ) that you want to find.
.
So, assume you know what x is.
.
Pretend it's 10 or like infinity or what-not.
.
So, x + $32.25 = $45.32.
.
But you don't know x.
.
But it's easy to find it.
.
Subtract $32.25 on both sides, and BOOM!!
.
Hope this helped!.

Any question, ASK AWAY!!
