Damm [24]

Answer:

b=1

Step-by-step explanation:

2b+1+2b=3b+2b

4b+1=5b(Simplify both sides of the equation)

4b+1−5b=5b−5b(Subtract 5b from both sides)

−b+1=0

−b+1−1=0−1(Subtract 1 from both sides)

−b=−1

−b

−1

=

−1

−1

(Divide both sides by -1)

b=1

Check answers. (Plug them in to make sure they work.)
