Question

- 3(x + 7) - 3x - 18 ? Please I really need help because our long-term sub won’t explain it in a way I can understand

Answer 1

-6x - 39

Explanation:

-3(x + 7) -3x -18 Fist distribute the -3

-3(x) + -3(7) -3x -18 Simplify (a negative times a positive is a negative)

-3x -21 -3x -18 Now combine like terms

-6x -39
