#### Explanation:

Remember: In an expression, a variable can have any value. You can only solve it when you give it a value.

So the problem is asking us what are the answers if we were to give the $x$ the values of 1,2, and 3. We simply replace $x$ with the numbers.

$- 3 x + 2$ is now
$- 3 \left(1\right) + 2$ for $x = 1$
$- 3 \left(1\right) + 2 = - 1$

$- 3 x + 2$ is now
$- 3 \left(2\right) + 2$ for $x = 2$
$- 3 \left(2\right) + 2 = - 4$

$- 3 x + 2$ is now
$- 3 \left(3\right) + 2$ for $x = 2$
$- 3 \left(3\right) + 2 = - 7$

$- 3 \left(1\right) + 2 = \left(- 1\right)$
$- 3 \left(2\right) + 2 = \left(- 4\right)$
$- 3 \left(3\right) + 2 = \left(- 7\right)$

#### Explanation:

Substitute the x values for the expression
