Answer 6

In the expression \( 3x - 10 + 2y + 5 \), the variables are \( x \) and \( y \). The expression can be simplified further to \( 3x + 2y - 5 \), but the variables remain \( x \) and \( y \).

Answer 7

In the expression \( 3x - 10 + 2y + 5 \), we can identify the coefficients and constants as follows:

### Coefficients:
- The coefficient of \( x \) is \( 3 \).
- The coefficient of \( y \) is \( 2 \).

### Constants:
- The constants in the expression are \( -10 \) and \( +5 \).
- When combined, they simplify to \( -5 \) (i.e., \(-10 + 5 = -5\)).

So, to summarize:
- **Coefficients:** \( 3 \) (for \( x \)) and \( 2 \) (for \( y \))
- **Constant:** \( -5 \) (after combining \(-10\) and \(5\))

Answer 8

To simplify the expression \( 7(2x - 4) \) using the distributive property, you will multiply \( 7 \) by each term inside the parentheses:

\[
7(2x) - 7(4)
\]

Now perform the multiplication:

\[
= 14x - 28
\]

So, the simplified expression is \( 14x - 28 \).

Answer 9

To simplify the expression \( 7(2x - 4) \) using the distributive property, you multiply \( 7 \) by each term inside the parentheses:

\[
7(2x) - 7(4)
\]

This results in:

\[
= 14x - 28
\]

Thus, the simplified expression is

\[
\boxed{14x - 28}
\]

Answer 10

To solve the equation \( \frac{x}{4} + 9 = 12 \), follow these steps:

1. **Subtract 9 from both sides** to isolate the term with \( x \):

\[
\frac{x}{4} + 9 - 9 = 12 - 9
\]

This simplifies to:

\[
\frac{x}{4} = 3
\]

2. **Multiply both sides by 4** to solve for \( x \):

\[
4 \cdot \frac{x}{4} = 3 \cdot 4
\]

This simplifies to:

\[
x = 12
\]

So the solution to the equation is

\[
\boxed{12}
\]

Answer 11

To find the undefined value for the equation \( \frac{8}{x} - 15 = 13 \), we first need to set the denominator of the fraction equal to zero, as that will make the expression undefined.

The denominator in this case is \( x \). Therefore, the expression is undefined when:

\[
x = 0
\]

Thus, the undefined value for the expression \( \frac{8}{x} - 15 = 13 \) is

\[
\boxed{0}
\]

If you want to simplify the equation or solve it, here's how you would do it:

1. Start by adding \( 15 \) to both sides:

\[
\frac{8}{x} = 13 + 15
\]
\[
\frac{8}{x} = 28
\]

2. Then multiply both sides by \( x \):

\[
8 = 28x
\]

3. Finally, solve for \( x \):

\[
x = \frac{8}{28} = \frac{2}{7}
\]

However, the only undefined value for this equation remains \( x = 0 \).
