Question

Math 7a using number sense to solve equations

Answer 1

Simple...

you have:
`(n)/(3) =12`

and


`(n)/(3) =-12`

To solve for....
`(n)/(3) =12`

Multiply to remove the denominator-->>


`3* (n)/(3) =12*3`

n=12*3

n=36

Then-->>>


`(n)/(3) =-12`

Do the same thing-->>


`3* (n)/(3) =-12*3`

n=-12*3

n=-36

Thus, your answer.
