let c = cory's age now
let s = her sisters age now
cory's age now = sisters age + 6 years
=> c = s + 6
4 years ago, cory was 4 years younger ( i.e. c-4) and her sister was 4 years younger (s- 4)
4 years ago cory was 4 times older than her sister
=> c - 4 = 4*(s-4)
We can simplify this to
c = 4s - 16 +4
c = 4s - 12
We can then use simultaneous equations to solve the two equations
(i) c = s + 6
(ii) c = 4s - 12
If we multiply both sides of equation (i) by 4 we get
(iii) 4c = 4s + 24
We can then subtract equation (ii) from equation (iii) to eliminate the '4s' term
=> ( 4c = 4s + 24 ) - (c = 4s - 12)
=> 4c - c = 4s +24 - 4s +12
=> 3c = 4s - 4s +36
=> 3c = 36
=> c = 36/3
=> c = 12
=> Cory's age now = 12
Her sister's age now is of course 6
4 years ago Cory would of been 8 and her sister would of been 2
I hope this helps and good luck! If you have more questions - ask away!

Many Thanks Don.
First we have 2 variables, their ages: I used Allan = x & Roy = y
Equation 1: X - 4 = 2*(Y-4) - 3
We can ignore the 5 years in the second part of the statement. Allan will always be 6 years older than Roy whether it be 5 years from now or ten years form now.
Equation 2: X = Y + 6
Substitute Y + 6 for X in equation 1:
X - 4 = 2*(Y-4) - 3 becomes Y + 6 - 4 = 2*(Y-4) - 3
That simplifies to Y + 2 = 2Y - 8 - 3
Rewrite it again: Y + 2 = 2Y - 11
Add 11 to both sides: Y + 13 = 2Y
Subtract Y from both sides: 13 = Y
Now plug 13 in for y in Equation 2
X = Y + 6
X = 13 + 6
X = 19

The problem is that the lens has become stuck in the barrel. There are some DIY solutions you could try, but the
probability is that you will have to get it fixed by a professional.
these at own risk as it may further damage the camera.
try connecting your ac adapter or usb cable.
Try holding the
shutter button while switching on the camera.
Look at the lens ,
and if some of the lens 'circles' is misaligned or not concentric then
try wiggling it (while holding camera lens down).
pushing or pulling the lens when it extends but this is risky as it may
cause the lens barrel to slip out of its guidance system.
way to do this is to place the camera lens down on a hard surface and
then power it up. Be sure to use a soft cloth or something similar as to
not scratch your lens or casing. Let the lens push the camera up and
down a few times and sometimes the little resistance provided by the
camera is enough to get things going again.
Try hitting your
camera near the lens on the body with the soft tissue on the palm of
Other than that , I would take the camera to a repair
center for a evaluation to see if it would cost more to repair than to
replace the camera.
If it is still under warranty I would suggest
you take it in before trying any of these steps and remove any
off-brand batteries or accessories as some stores are really fussy about
warranty repairs on camera's with non-brand accessories.
sometimes, this is happens when your cd drive has a weak lens or the disc you are using is faulty.... check the disc..... try to create an image of the disc using another powerful writer .... if the image creation is successful, then use the image by mounting on your machine instead of the disc....
unfortunately there is no way around it as the software is not compatible with vista and wasn't designed for vista, i had a similar old software installed fine with vista but this is not true for most of them
