Answer:

He bought 16 books

Step-by-step explanation:

cost = flat fee + books * cost per book

133 = 5 +b*8 where b is the number of books

133 = 5+8b

Subtract 5 from each side

128 = 8b

Divide each side by 8

128/8 = 8b/8

16 = b

He bought 16 books

One day, a person went to a horse racing area. Instead of counting the number of humans an horses, he conuted 74 heads and 196 l
DerKrebs [107]
Data:

Humans (x) = 2 Legs
Horses (y) = 4 Legs

74 Heads
196 Legs

Solving:

Addition method

\left \{ {{x + y =74} \atop {2x + 4y =196}} \right.

Simplify by (-4) The first equation

\left \{ {{x + y =74(-4)} \atop {2x + 4y =196}} \right.
\left \{ {{-4x - \diagup\!\!\!\!\!4y =-296} \atop {2x + \diagup\!\!\!\!\!4y =196}} \right.
\left \{ {{-4x =-296} \atop {2y =196}} \right.
-2x = -100.simplify(-1)
2x = 100
x = \frac{100}{2}
\boxed{x = 50}

Now, to find the number of horses, I will use the following equation and I will replace the found value, we will have:

x + y = 74
50+y = 74

Number with incognito are to the left of the equality and numbers without incognito are to the right, remembering that when changing of side changes the signal.

y = 74-50
\boxed{y = 24}

Answer:
Humans = 50
Horses = 24
