Answer by richwmiller(17219) (Show Source): You can put this solution on YOUR website!
2b+4(b-1)=5(b-1)
there are at least two ways to do this. one easy and one easier
we can subtract 4(b-1) from both sides
2b=1(b-1)
2b=b-1
subtract b from both sides
b=-1
another way
2b+4(b-1)=5(b-1)
expand
2b+4b-4=5b-5
combine like terms
6b-4=5b-5
subtract 5b from both sides
b-4=-5
add 4 to both sides
b=-1

Multiply 4 times b and 4 times -1:

Multiply 5 times b and 5 times -1:

Add -5b to both sides:

And collect like terms:

Add 4 to both sides:

Check:

Yep, every time.
