# 2b+6.7=12.9

Get (2b) by itself. So, do the opposite of addition, which is subtraction. Subtract 6.7 on both sides.

2b + 6.7 - 6.7 = 12.9 - 6.7

**2b = 6.2**

Now, divide by 2 on both sides to get (b) by itself.

2b/2 = 6.2/2

**b = 3.1**

**Check your answer: Rewrite the problem and put (3.1) in place of (b).**

2(3.1) + 6.7 = 12.9

6.2 + 6.7 = 12.9

** 12.9 = 12.9**
