This is because the expression can be simplified to get the same result. -1+2log_4((1/4)x)
Here is the answer I believe. It goes in a x all it did was added to to each x and y (-3,0)
Ratio 9:13:18......added = 40. This means that one person gets 9/40 of the total, one person gets 13/40 of the total and one person gets 18/40 of the total.
and if the total is 800...
9/40 * 800 = 7200/40 = 180 <==
13/40 * 800 = 10400/40 = 260 <==
18/40 * 800 = 14400/40 = 360 <==
Hi!
When multiplying by ten, the decimal moves one space to the right.

I also included an image showing the decimal place moved to the right.
Hope this helps! :)
