0.5b + 4 = 2(b + 2)

Question

A. b = 0
B. b = 0.5
C. no solution
D. identity

Answer 1

To solve the equation, we can start by distributing the 2 to (b+2) on the right side:

0.5b + 4 = 2b + 4

Next, we can subtract 0.5b from both sides to isolate the term with b:

4 = 1.5b + 4

Now, we can subtract 4 from both sides:

0 = 1.5b

Finally, we can divide both sides by 1.5 to solve for b:

0/1.5 = b

0 = b

So, the solution is b = 0.

Therefore, the correct answer is:

A. b = 0
