Answer:
b = -28
Explanation:
You will solve for b:
-b/7=4
Multiply both sides by 7 to eliminate the fraction.
-b = 7·4
-b = 28
Divide both sides by -1 to eliminate the negative, since the variable can't be a negative. This will get you your answer.
-b · -1 = 28 · -1
b= -28
To check your answer, plug in answer to the variable:
-(-28)/7 = 4
28/7 = 4
4 = 4 ✓
