You're both incorrect.....

It's.......  22 poo........

That answer is not quite correct, Melody.......

The true answer is .........12 POO !!!!

2 poo ????

One problem here is that the exponent on the left side (.5) doesn't equal the exponent on the right side (.5 x10) = 5

As Alan has said, the first thing gives you ≈ 659.5

But, 400e⁵  ≈ 59365.26  !!!

So, since it's linear, I assume we have

(2/5)(x-1) + (5/2)(x+2) = (3/2)(x-2)

Let's multiply through by the LCM of 2 and 5 (i.e., 10) to clear the fractions...this gives

4(x-1) + 25(x + 2)  = 15(x-2)          simplify

4x - 4 + 25x + 50  = 15x - 30          combine like terms

29x + 46 = 15x - 30          subtract 46 from both sides and subtract 15x from both sides

14x = -76                                  divide both sides by 14

x = -76/14  = -38/7

Well....this is a sad day for us, DS!!!.......you are a real joy to have on the forum.......come back when you can.........there will ALWAYS be a place "saved" for you.

Here's a special send off.......as rosala would say......"CPhill style"

46 = 23 x 2

Both 23 and 2 are prime......so that's all we can do......neither of the prime factors are "raised" to any higher power than 1

We tried to track down Anonymous to "remove" him/her..........but, we couldn't find any phone book listing for such a person.......apparently, "Anonomous" is one slippery character !!!......I guess it's true what they say, "You can catch the Devil.......but you can never hold him."
