Answer:
6
Step-by-step explanation:
Let x be the number Albert thought about.
1. Albert thought of a number, added 5, then he got x+5.
2. Albert  multiplied the result by 2, then he got 2(x+5).
3. He took away 6, then the number became 2(x+5)-6.
4. Albert divided the result by 2 to get the number
[tex]\dfrac{2(x+5)-6}{2}[/tex]
that is 8.
5. Thus, you can state that
[tex]\dfrac{2(x+5)-6}{2}=8,\\ \\2(x+5)-6=16,\\ \\2(x+5)=16+6,\\ \\2(x+5)=22,\\ \\x+5=22:2,\\ \\x+5=11,\\ \\x=11-5,\\ \\x=6.[/tex]
