The total depreciation is 12500 - 3000 = 9500
Yearly rate = 9500/5 = 1900

Current value = Original value - (Yearly rate of depreciation)*(number of years)
Subtract $12,500 from both sides to separate the variable
$3000 = $12500 - R * 5 years
-$12500 -$12500
Divide both sides by - 5 years to solve for R.
-$9500 = - R * 5 years
/-5 years /-5 years
$ 1900 / year = R
Big Daddy's method is exactly the same, just done in a different order, and is equally valid.

Well...let's start!
You get the total depreciation by 12500 - 3000 = 9500
You get the yearly rate by 9500/5 = 1900

Start with 5x+3000=12,500
Divide out 5 so it looks like
5x + 3000 = 12500
____________
5
That will give you x + 600 = 2500
Subtract 600 from both sides
x+600 -600 = 2500 - 600
x = $1900
To check your work. Times 5 (the number of years) by x ($1900) and add $3000...which = $12,500

yearly amt = Y
12500 - (5y) = 3000
9500 = 5y
y = 9500/5 = 1,900
