L x - 2 l = l 4 + x l
Remember : Absolute is just the distance from zero.
Ex : l -4 l turns into 4, as it is 4 spaces away from zero on a number line :)
l x - 2 l turns into x + 2
l 4 + x l stays the same.
So, our equation now looks like this :
x + 2 = 4 + x
So, we're basically just trying to get x by itself.
So, subtract 2 from both sides.
x = 4 + x - 2
Then, subtract x from both sides.
x - x = 4 -2
0 = 2
Therefore, there are no solutions to this equation :)

they were asking you about the rate of increase in students per year
so you take increase in students/years= (224-120)/(2005-1992)=104/13=8
Answer:
There is one solution
Step-by-step explanation:
15x+11=8x
Subtract 15x from each side
15x-15x +11 = 8x-15x
11 = -7x
Divide by -7
11/-7 = -7x/-7
-11/7 =x
There is one solution
It's 67/100 because a percent is out of 100 which is already simplified
Answer: 1 hour 20 minutes

Let's figure out how long it would take 1 person to dig the hole and then divide that number by 9 (since they are sharing the workload).
