Answer 2

Solving the Problem

To solve this problem, we can use a system of equations. Let's denote the initial number of books in the first cabinet as x and the initial number of books in the second cabinet as y. We are given that the total number of books in both cabinets is 1000, and after taking 147 books from the first cabinet and 49 books from the second cabinet, the remaining books in both cabinets are equal.

We can set up the following equations based on the given information:

1. x + y = 1000 (total number of books in both cabinets) 2. (x - 147) = (y - 49) (remaining books in both cabinets are equal)

Let's solve these equations to find the values of x and y.

Solution

Using the first equation, we can express y in terms of x: y = 1000 - x

Substituting this value of y into the second equation: (x - 147) = (1000 - x - 49)

Solving for x: x - 147 = 1000 - x - 49 2x = 1000 + 147 - 49 2x = 1098 x = 549

Now that we have the value of x, we can find the value of y: y = 1000 - x y = 1000 - 549 y = 451

Answer

So, after solving the equations, we find that there were 549 books in the first cabinet and 451 books in the second cabinet initially.

Therefore, after taking 147 books from the first cabinet and 49 books from the second cabinet, there are 402 books left in the first cabinet and 402 books left in the second cabinet.
