If you have
|a|=b
assume
a=b and -a=b

|x-2|=3x-4
assume
x-2=-3x-4
-(x-2)=3x-4
solve each


x-2=3x-4
minus x from both sides
-2=2x-4
add 4 to both sides
2=2x
divide both sides by 2
1=x

-(x-2)=3x-4
-x+2=3x-4
add x to both sides
2=4x-4
add 4 to both sides
6=4x
divide both sides by 4
1.5=x

x=1 or 1.5

(4) |-5 + (-2)| _____ |5 + 2| <br> &lt;<br> &gt;<br> =
nikitadnepr [17]

Hi

The answer would be =

Why?

The `| |` symbols mean actual value, which makes every number inside of it positive. That would mean, following the rules of actual value, the equation would look like:

5 + 2 _____ 5 + 2

Both add up to 10, so both equations are equal.
