Answer 1

34

Explanation:

Answer 2

`\huge{\boxed{r=34}}`

First, let's write this as an equation. The sum (addition) of
`\bf{r}` and
`\bf{45}` is [equal to]
`\bf{79}`.

`r+45=79`

Now, we need to get the variable by itself on one side of the equals sign. We can do this by subtracting
`45` from each side.

`\boxed{r=34}`
