в 4 я не особо поняла что там написано

Answer 2

Ответ:

1. x = 116 (выразили x)

2. x = 25 (выразили x)

3. y = 179 (выразили y)

4. y = 66 (выразили y)

Answer 3

It seems like you've provided four equations, and it looks like you want to solve for the variables 'x' and 'y' in each equation. Let's solve them one by one:

1. $321 + (x + 13) = 450$ To solve for 'x', first simplify the equation:

$$321 + x + 13 = 450$$

Combine like terms:

$$x + 334 = 450$$

Subtract 334 from both sides:

$$x = 450 - 334 x = 116$$

So, $x = 116$.

2. $204 - (x + 29) = 100$ To solve for 'x', first simplify the equation:

$$204 - x - 29 = 100$$

Combine like terms:

$$- x + 175 = 100$$

Subtract 175 from both sides:

$$- x = 100 - 175 - x = -75$$

Now, multiply both sides by -1 to isolate 'x':

$$x = 75$$

So, $x = 75$.

3. $122 + (y - 7) = 200$ To solve for 'y', first simplify the equation:

$$122 + y - 7 = 200$$

Combine like terms:

$$y + 115 = 200$$

Subtract 115 from both sides:

$$y = 200 - 115 y = 85$$

So, $y = 85$.

4. $53(y - 13)$ This equation does not have an equal sign, so it's not possible to solve for 'y' without additional information or context.

So, the solutions are:

1. $x = 116$
2. $x = 75$
3. $y = 85$
4. Cannot solve for 'y' without additional information.
