Solution :

Let x be the number

[tex]\small\bold\red{→}\small\bold{(\frac{1}{2} )x + 5 = 11}[/tex]

[tex]\small\bold\red{→}\small\bold{(\frac{1}{2})x + 5 - 5 = 11 - 5}[/tex]

[tex]\small\bold\red{→}\small\bold{(\frac{1}{2})x = 6}[/tex]

[tex]\small\bold\red{→}\small\bold{2 × (\frac{1}{2})x = 6 × 2 }[/tex]

[tex]\small\bold\red{→}\small\bold{x = 12}[/tex]

Hello.

First, "half a number" means we divide that number by 2.

Let's say the number is z.

Divide z by 2:

[tex]\displaystyle\frac{z}{2}[/tex]

Add 5 to it:

[tex]\displaystyle\frac{z}{2} +5[/tex]

Now, this expression equals 11:

[tex]\displaystyle\frac{z}{2} +5=11[/tex]

Subtract 5 from both sides:

[tex]\displaystyle\frac{z}{2} =11-5[/tex]

[tex]\displaystyle\frac{z}{2} =6[/tex]

Now, in order to get rid of the fraction, we should multiply the entire equation by 2:

[tex]\displaystyle\frac{z}{2} *2=6*2[/tex]

[tex]z=6*2[/tex]

[tex]\Large\boxed{z=12}[/tex]

I hope it helps.

Have an outstanding day. :)
