Answer :
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
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.
