-8

Explanation:

Answer 2

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. :)
