Question

Solve the equation -8(n + 7) = -88. What are two ways to start solving this equation? Choose BOTH ways.

Answer 1

Answer:

Divide each side by -8

Distribute

Step-by-step explanation:

-8(n + 7) = -88.

Method 1

Divide each side by -8

n+7 = 11

Subtract 7 from each side

n = 4

Method 2

Distribute

-8n-56= -88

Add 56 to each side

-8n = -32

Divide by -8

n=4

Answer 2

Answer:

Distributive property & dividing -8 on both sides.

Step-by-step explanation:

You can begin solving the equation by either using the distributive property or dividing -8 on both sides.

Distributive Property:

$-8(n+7)=-88\\-8n-56=-88\\-8n=-32\\n=4$

Dividing:

$-8(n+7)=-88\\n+7=11\\n=4$
