I'm guessing we are solving for x.
Let's write it properly:
[tex] \frac{x}{2}+6=12 [/tex]
To solve for x, we must isolate it (subtract 6 from both sides to get rid of it):
[tex] \frac{x}{2}+6-6=12-6[/tex]
[tex] \frac{x}{2} =6[/tex]
Multiply by 2 (inverse of division) to get rid of it:
[tex] \frac{x}{2}*2 = 6*2 [/tex]
[tex]x =12[/tex]
So, our final answer is x = 12
