Answer:
x = -7
Step-by-step explanation:
Use the distibutive property on both side:
Right side:
4 ( 1 - x )
( 4 x 1 ) + 4 x -X )
4 - 4x
Left side:
-3 ( x + 1 )
( -3 x X ) + ( -3 x 1 )
-3x -3
4 - 4x + 2x = -3x - 3
Combine like terms:
( 2x + ( -4x ) ) + 4 = -3x - 3
-2x + 4 = -3x - 3
Add 3 to each side:
-2x + 7 = -3x
add 2x to each side:
7 = -x
Divide each side by -1:
-7 = x
A million seconds is not that long. My next birthday is in 1,296,000 seconds
from now, and I have already lived more than 2.3 billion seconds !
(1,000,000 seconds) x (1 day / 86,400 seconds) =
11days 13hours 46minutes 40seconds .
It's possible that you might have one birthday within that length of time,
but it's not guaranteed. It would have to be the RIGHT million seconds.
If that's been your whole life so far ... you are 1 million seconds old ..,
then you have not had your first birthday yet.
