Answer 2

Hi there!


`5( - 3x - 7) =`
To find our answer we need to work out the parenthesis. This can for instance be done using rainbow technique.


`5 * - 3x + 5 * - 7 =`
Now multiply. Remember that multiplying a negative by a positive makes you end up with a negative.


`- 15x - 35`
The fourth answer is correct.
