Question

Math 7a using number sense to solve equations

Answer 1

Simple...

you have: $\frac{n}{3} =12$

and

$\frac{n}{3} =-12$

To solve for....$\frac{n}{3} =12$

Multiply to remove the denominator-->>

$3* \frac{n}{3} =12*3$

n=12*3

n=36

Then-->>>

$\frac{n}{3} =-12$

Do the same thing-->>

$3* \frac{n}{3} =-12*3$

n=-12*3

n=-36

Thus, your answer.
