Question

solve the equation 8(n + 7) = 88.
what are two ways to start solving this equation? choose both ways.
use the associative property.
use the distributive property.
subtract 7 from both sides.
subtract 8 from both sides.
divide both sides by 8.
divide both sides by 88.

Explanation:

To solve \(8(n + 7)=88\), one way is to use the distributive property (\(a(b + c)=ab+ac\)) to expand \(8(n + 7)\) to \(8n+56\). Another way is to divide both sides by 8 to isolate the \((n + 7)\) term, as dividing both sides by the coefficient of the parenthetical expression simplifies the equation. The associative property is not relevant here, subtracting 7 or 8 from both sides is incorrect (since 7 is inside the parentheses and 8 is a coefficient of the parenthetical), and dividing by 88 is not a useful first step.

Answer:

B. Use the distributive property, E. Divide both sides by 8
