5 or 2

parthkohli · Answer

Add 8 to both sides first.

$ \color{Black}{\Rightarrow |2x - 3| = 7 }$

So, $2x - 3 = \pm 7$

parthkohli · Answer

Two equations to solve here:

$ \color{Black}{\Rightarrow 2x - 3 = 7 }$
$ \color{Black}{\Rightarrow 2 x - 3 = -7 }$

why dont you go for option checking instead of actually solving!! (saves time) ;)

lgbasallote · Answer

^that depends lol

sriram · Answer

means 2x-3=7 or -7
hence solving it we get 
2x=10 or -4
giving 
x=5 or -2

lgbasallote · Answer

some people can solve this faster than checking blindly ;)

parthkohli · Answer

I think that understanding is the key factor and solving it is the best way to understand the problem. I prefer solving rather than checking.
