10y + 8
7n + 6y + 3 – 2n + 4
7n + 6y + 3 – 2n + 4
5n + 6y + 7
3r -2r + 5
3r -2r + 5
r + 5
4n + 6m + n - 2m + 2
4n + 6m +n - 2m + 2
4m + 5n + 2
2x + 7 + 5x - 4 - x
2x + 7 + 5x - 4 - x
6x + 3
What if our expression looks like this….
6(b + 2) How could we simply this
expression?

Let’s practice.
4(6 + k)
4 (6) + 4 (k)
24+4k
