negative times a negative makes a positive
so we can get
B + 7 = -1
then subtract 7 from both sides
B = -1 - 7 = -8

therefore B = -8

B-(-7)= -1

First negative multiply by negative is POSITIVE.

So: B+7= -1

Subtract 7 from both sides

B= -7-1

B= -8.

Answer: -8.

To Check Answer: Plug in the variable of B in the original equation.

So: -8-(-7)= -1

-8+7= -1

-1= -1

If the Solution works out the answer is right.
