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
