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.
