Answer: x=12
Step-by-step explanation:
You start with: [tex]2x\neq 2x-12[/tex]
The segment PQ is half of PR, so to make both sides equal the PQ side must be doubled.
[tex]2x=4x-24[/tex]
Then all x-values should be put on one side of the equation.
[tex]2x-4x=-24[/tex]
Combine like terms.
[tex]-2x=-24[/tex]
Then simplify.[tex]x=12[/tex]
