Question

Using the properties of equality to solve the equation -2b + 7 = -13, you would _____.

A.) add 13 and then divide by -2
B.) subtract 7 and then add 2
C.) subtract 7 and then divide by -2
D.) add 13 and then add 2
this is multiple choice

Answer 1

Answer:
c. subtract 7 from both sides and then divide both sides by -2

Step-by-step explanation:
Step 1 - Subtract 7 from both sides
-2b + 7 = -13
-2b + 7 - 7 = -13 - 7
-2b = -20

Step 2 - Divide both sides by -2
-2b = -20
-2b / -2b = -20 / -2b
b = 10

Answer 2

Subtract 7 from each side

Divide each side by -2

Step-by-step explanation:

-2b+7 = -13

Subtract 7 from each side

-2b+7 -7= -13-7

-2b = -20

Divide each side by -2

-2b/-2 = -20/-2

b = 1-
