Simplifying 8x + -4 = 3x + 17 Reorder the terms: -4 + 8x = 3x + 17 Reorder the terms: -4 + 8x = 17 + 3x Solving -4 + 8x = 17 + 3x Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-3x' to each side of the equation. -4 + 8x + -3x = 17 + 3x + -3x Combine like terms: 8x + -3x = 5x -4 + 5x = 17 + 3x + -3x Combine like terms: 3x + -3x = 0 -4 + 5x = 17 + 0 -4 + 5x = 17 Add '4' to each side of the equation. -4 + 4 + 5x = 17 + 4 Combine like terms: -4 + 4 = 0 0 + 5x = 17 + 4 5x = 17 + 4 Combine like terms: 17 + 4 = 21 5x = 21 Divide each side by '5'. x = 4.2 Simplifying x = 4.2

Hope this helps :)

On a particularly boring transatlantic flight, one of the authors amused himself by counting the heads of the people in the seat

xxTIMURxx [149]

Answer:

The answer is 5.

Step-by-step explanation:

Total number of people noticed by author = 28

Total number of black haired people = 27

So, total number of non black haired people = 1

Also given that 6 people had whole row of seats to themselves.

Let x be the number of non black haired people who had a whole row to themselves.

Since there is only one person with non black hair and has a whole row to himself because it is mentioned that one person had a row to himself which is non black haired.

Looking at above information we can say that x = 1.

Now we can say that the number of black haired people who had a whole row to themselves = 6-x

or $6-1=5$

Hence, the answer is 5.
