Answer:
The value of b would be -8.
b = -8
Explanation:
To find the value of b by using the equation b - 4 = -12, you would get the equation into the form b = _. That _ would be the value of b.
When solving for a variable in an equation, you must do to one side what you do to the other side of the equation.
b - 4 = -12
Add 4 to both sides to get rid of the -4 on the left side of the equation.
b - 4 + 4 = -12 + 4
Simplify
b = -8
So the value of b would be -8.
I hope this helps. :)
