х+х-3+х+8=62
3х+5=62
3х=57
х=29 тет. у Кати.

Answer 2

Solving the word problem step-by-step:

The question states that: Katya had x notebooks. Sergey had 8 more notebooks than Katya. Sveta had 3 notebooks less than Katya. The total number of notebooks of all three was 62.

Let's break this down: 1) Let x = the number of notebooks Katya had 2) Sergey had 8 more than Katya, so Sergey had x + 8 notebooks 3) Sveta had 3 less than Katya, so Sveta had x - 3 notebooks 4) We know: Katya's notebooks (x) + Sergey's notebooks (x + 8) + Sveta's notebooks (x - 3) = Total notebooks (62) 5) So: x + (x + 8) + (x - 3) = 62 6) Simplifying: 3x + 5 = 62 7) Subtracting 5 from both sides: 3x = 57 8) Dividing both sides by 3: x = 19

Therefore, if the total notebooks was 62 and the information given is correct, the number of notebooks Katya had was 19.
