Question

How would I solve |2x-4|=5?

Answer 1

Make 2 seperate equtions and solve
1. 2x-4=5
2. 2x-4=-5

Answer 2

You can split in two equations. First you need to know where 2x-4 change its sign.

\[2x-4=5\Rightarrow x=9/2\]Now you have to solve simultaneously two equations,
\[x\geq9/2\Rightarrow2x-4=5\]\[x<9/2\Rightarrow -(2x-4)=5\]Remember to check that the solutions lies in the cited interval.
