Hi there! :)
Answer:
b=19
*The answer must have a positive sign.*
Step-by-step explanation:
Lesson: Addition/Subtraction/Multiplication/ and Division property of equality
First, you add by 7 from both sides of an equation.
[tex]b-7+7=12+7[/tex]
Then, you add by the numbers from left to right.
[tex]12+7=19[/tex]
Final answer is b=19
I hope this helps you!
Have a nice day! :)
