Question

Simplify the following expression by combining like terms:



`-3\left(10b+10\right)+5\left(b+2\right)-6\left(b-2\right)+10-16b`

Answer 1

First expand each product:

-3(10b+10) = -30b - 30
5(b+2) = 5b + 10
-6(b-2) = -6b + 12

Now combine all terms:
(-30b + 5b - 6b - 16b) + (-30 + 10 + 12 + 10)
= -47b + 2

So the simplified expression is -47b + 2.
