105.9 + 7.25 + .815 + 12.63 =  126.595

And there you go !!!

The greatest common divisor of 18 and 48 is 6.....so we have

(3 * 6) / (8 * 6)     and "cancelling" the 6s on top and bottom leaves us with  3/8

First step:  Untatum derivis excaliber ovisanctus......

Second step: Nitroglycerus explodum dynamitus grenadeium boom !!!!

P.S.  -  If you can translate yours, I'll happily translate mine...!!!

No...I don't think -2 will work....let's see

-2x+13+4x=12     simplify on the left

2x + 13 = 12        subtract 13 from both sides

2x = -1                divide by 2 on both sides

x = -1/2

Yeah....that's it !!!

I know that higher-level engineers like yourself don't like to admit to trade secrets....but how/where did you get that "running" banana thingy ????   Priceless!!!

This question is impossible to answer....oh, wait!!!.....I guess that actually makes it possible to answer, since everything is possible !!!

Eh, heck......I'm getting cofused, myself !!!!!

7x-(x+4)=-7   I think you'd actually want to solve this !!!  ...... simplify first........

7x - x - 4 = -7

6x - 4 = -7      add 4 to both sides

6x = -3          divide both sides by 6

x = -3/6 = -1/2

We can model this with the following exponential function:

A = 100(.90)ⁿ    where A is the value of the account after n withdrawals

So, after 10 witdrawals,we have

A = 100(.90)¹⁰ = $34.87  left after 10 withdrawals

This seems counter-intuitive....but we are withdrawing 10% of a smaller and smaller balance  as n increases. Theoretically, since an exponential function is never 0, the account is never emptied - there always remains some fraction of one cent, even after infinite withdrawals !!!! (However, the limit of this fuction as n approaches infinity = 0)
