Пошаговое объяснение:

(6x + 15)/8 - (10x + 14)/3 = (7x - 105)/4 - 21/4 (домножим на 24)

3*(6x + 15) - 8*(10x + 14) = 6*(7x - 105) - 6*21

18x + 45 - 80x - 112 = 42x - 630 - 126

-62x - 67 = 42x - 756

42x + 62x = 756 - 67

104x = 689

x = 689 : 104

x = 6,625

================ и если это 6цел.7/8

(6x + 15)/8 - (10x + 14)/3 = (7x - 105)/4 - 55/8 (домножим на 24)

3*(6x + 15) - 8*(10x + 14) = 6*(7x - 105) - 3*55

18x + 45 - 80x - 112 = 42x - 630 - 165

-62x - 67 = 42x - 795

42x + 62x = 795 - 67

104x = 728

x = 728 : 104

x = 7

Answer 3

<br /> is an HTML tag used to create line breaks in a web page. It is a self-closing tag, meaning it does not require a closing tag.

When you use <br /> in your HTML code, it inserts a line break at that point. This can be useful for separating paragraphs, creating space between lines, or inserting a blank line.

Here's an example of how you can use <br /> in HTML:

phpCopy code
<p>This is the first line.<br />
This is the second line.</p>

In this example, the <br /> tag is placed between the two lines of text within the paragraph element. When the page is rendered, it will display as:

arduinoCopy code
This is the first line.
This is the second line.

Each <br /> tag creates a single line break. If you want to insert multiple line breaks, you can use multiple instances of the <br /> tag.

It's worth noting that using <br /> excessively for layout purposes is generally discouraged in modern web development. Instead, it's recommended to use CSS for styling and layout, and reserve line breaks for separating meaningful sections of content.
