Does someone mind helping me with this question? Thank you!

Answer 1

• 
  `\bf -20`

Explanation:

`\bf 2(xy-7)`
`\bf when`
`\bf x=-1/y=3`

Substitute with x and y with 3:-

`\bf 2\left(\left(-1\right)(3)-7\right)`

First, Multiply -1 and 3 = -3

`\bf 2(-3-7)`

Subtract 7 from -3 = -10

`\bf 2(-10)`

Multiply 2 and -10 = -20

`\bf -20`
