Dan has $ 33. He bought some candy bar for $ 32 each one costing $ 1. How many candy bar did he buy?
Dan has $33. 
He buys candy bars for $32 each. 
Each candy bar costs $1. 

We want to know how many candy bars he bought. 

We can set up an equation to solve this problem: 

$33 = $32x + $1x

$33 = $32x + $1x
$33 - $1x = $32x
$1x = $33 - $32x
$1x = $1(33 - 32x)
$1x = $1(33 - $32x)
$1x = $1($33 - $32x)
$1x = $1($33 - $32x)
$1x = $1($33 - $32x)
$1x = $1($33 - $32x)
$1x = $1($33 - $32x)

$1x = $1($33 - $32x)
$1x = $1($33 - $32x)
$1x = $1($33 - $32x)

$1x = $1($33 - $32x
