Answer:
x = 6/5 or x = -2
Step-by-step explanation:
We need to solve:
|5x+2|=8
We know that |u|=a the u = a and u = -a
Now solving:
|5x+2|=8
5x +2 = 8 or 5x +2 = -8
5x = 8-2 or 5x = -8-2
5x = 6 or 5x = -10
x = 6/5 or x = -10/5
x = 6/5 or x = -2
So, x = 6/5 or x = -2

- The first page can be represented by 2n
(Note : We know for certain it is an even number as anything multiplied by 2 is even)
The second page can be represented by 2n + 2
Let's form an equation:
2n + 2n + 2 = 410
Simplify by collecting like terms :
4n + 2 = 410
Subtract 2 from both sides :
4n = 408
Divide both sides by 4:
n = 102
Substitute this value into our earlier expressions
2(102) = 204
2(102) + 2 = 206
The page numbers are 204 and 206
