Question

За вечер братья прочитали 150страниц, причём Ваня прочитал на 40страниц меньше,чем Вова. Сколько страниц прочитал Ваня,а сколько Вова?

Answer 1

150-40=110
110:2=55 (ст) прочитал Ваня
55+40=90 (ст) прочитал Вова

Answer 2

х+х+40=150

2х=110

х=55

ваня 55 а вова 95

Answer 3

Let's use algebra to solve the problem. Let's represent the number of pages Vova read as V and the number of pages Vanya read as V - 40 (since Vanya read 40 pages less than Vova).

According to the given information, Vova and Vanya together read 150 pages, so we can set up the following equation:

V + (V - 40) = 150

Now, let's solve for V:

2V - 40 = 150 2V = 150 + 40 2V = 190 V = 190 / 2 V = 95

Now that we have Vova's pages, we can find Vanya's pages:

Vanya's pages = V - 40 = 95 - 40 = 55

So, Vova read 95 pages, and Vanya read 55 pages.
