The first answer is -15-20x.
The second answer is -42b-21.
Ask in the comments section if you want me to explain, other than combining like terms and using the distributive property. I hope this helps!

The first one is -15-20x. This is because you are distributing the 5 to the numbers that are in the paranthesis. So -5 times 3 is 15. -5 times 4x is -20x. For the second you do the same thing and multiply 7 by -6b and -3 so it would be -42b-21
