Question #4be45

Answer 1

Read below.

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.

`-3x+2` is now
`-3(1)+2` for `x=1`
`-3(1)+2=-1`

`-3x+2` is now
`-3(2)+2` for `x=2`
`-3(2)+2=-4`

`-3x+2` is now
`-3(3)+2` for `x=2`
`-3(3)+2=-7`

Answer 2

`-3(1)+2=(-1)`
`-3(2)+2=(-4)`
`-3(3)+2=(-7)`

Explanation:

Substitute the x values for the expression
