Answer:
6x <u>></u><u> </u> 3+4(2x -1)
6x <u>></u> 3+ 8x - 4
6x <u>></u> (-1) + 8x
6x - 6x <u>></u><u> </u> (-1) + 8x - 6x
subtracting 6x from both sides
0 <u>></u> 2x - 1
adding +1 on both sides
1 <u>></u> 2x
1/2 <u>></u> x
x <u><</u> 1/2
After 500 years one would have N nuclei of the original substance.
N = 100 * exp ( -ln(4) ) = 25
LOL.
I guess it is exp( - lamda * t)
Lamda, the decay constant is the ln(2) over the half life.
So we get exp( -ln(2)/250 * 500) or exp ( -ln(4) )

1/2x+y=-6 y=3/5x+5
substitute
1/2x+3/5x+5=-6
11/10x+5=-6
11/10x=-11
