Which expression can be used to check the answer to 56 divided by (negative 14) = n?

Natalka [10]

For this case we have the following expression:

$\frac {56} {- 14} = n$

To verify the answer we have:

Multiplying both sides of the equation by -14:

$- (14) * \frac {56} {- 14} = n * (- 14)\\56 = n * (- 14)$

Thus, the answer can be verified with:

$56 = n * (- 14)$

Answer:

$56 = n * (- 14)$
