Answer 1

1) b-(4-2b)+(3b-1)
b-4+2b+3b-1
6b-5
2) 4x-(1-2x)+(2x-7)
4x-1+2x+2x-7
8x-8=8(x-1)

Answer 2

I can help you simplify the expression. First, let's distribute the negative signs to remove the parentheses. We get:

$$b-4+2b-3b+1-4x+1-2x-2x+7$$

Then, let's combine the like terms. We get:

$$-2x+6b+9$$

This is the simplest form of the expression. I hope this helps.Ответь+подробно.+Помогите+упростите+выражение++b-(4-2b)+(3b-1)+4x-(1-2x)+(2x-7)
