Answer:

42

Step-by-step explanation:

Let the number be "x"

We translate the word equation to algebraic equation.

First,

subtract 6 from me, so we have:

x - 6

Now,

Multiply by 2, so we have:

2(x-6)

Now,

Subtract 40, then divide by 4:

[tex]\frac{2(x-6)-40}{4}[/tex]

Now, you get "8", so equate this to 8, we get:

[tex]\frac{2(x-6)-40}{4}=8[/tex]

We now solve using algebra:

[tex]\frac{2(x-6)-40}{4}=8\\2(x-6)-40=4*8\\2(x-6)-40=32\\2x-12-40=32\\2x-52=32\\2x=32+52\\2x=84\\x=42[/tex]

The number is 42
