[tex]\frac{x}{2}+1=9[/tex]
First you had to subtract by one from both sides of equation form.
[tex]\frac{x}{2}+1-1=9-1[/tex]
Then simplify.
[tex]\frac{x}{2}=8[/tex]
Next multiply by two from both sides of equation form.
[tex]\frac{2x}{2}=8*2[/tex]
You can also cross it out for [tex]\frac{2x}{2}[/tex].
Finally you simplify by equation.
[tex]8*2=16[/tex]
[tex]16/2=8[/tex]
[tex]2*8=16[/tex]
[tex]16/8=2[/tex]
[tex]x=16[/tex]
Final answer [tex]\boxed{x=16}[/tex]
Hope this helps!
