х-9*64=143
х-576=143
х=143+576=719 (п)

Answer 2

Problem Analysis

To solve this problem, we need to determine the total number of vacuum cleaners (пылесосы) that were initially on the factory (заводе) before 9 machines were taken away. We know that each machine had 64 vacuum cleaners, and there were 143 vacuum cleaners left on the factory.

Mathematical Equation

Let's represent the total number of vacuum cleaners on the factory as x. We can set up the following equation to solve for x:

x - (9 * 64) = 143

Solving the Equation

To solve the equation, we can simplify it and isolate x:

x - 576 = 143

Adding 576 to both sides of the equation:

x = 143 + 576

Simplifying:

x = 719

Answer

There were initially 719 vacuum cleaners on the factory.
