Solve the equation
So first we subtract 8 from both sides because we apply the inverse operation.
-2x+8=-16
-8 -8
Now we apply it and re write the equation
-2x=-24
Now the inverse operation for multiplication is division, so we apply it.
-2x=-24
------------
-2 -2
We are left with x=8
So our final answer is x=8
Check our work
-2(8)+8=-16
CORRECT ANSWER. :)
The answers is x =3 , x= -10
X=16 would not be true because it doesn’t work. X would equal 9.
Percent change = (new number - old number)/(old number) * 100
If the percent change is positive, it is a percent increase.
If the percent change is negative, it is a percent decrease.
In our case, the number goes from 500000 (the old number) to 60000 (the new number).
percent change = (new number - old number)/(old number) * 100
percent change = (60000 - 500000)/(500000) * 100
percent change = -88%
Answer: the percent decrease is 88%
