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
