What is the solution for this proportion?

n = -3

Step-by-step explanation:

Cross multiply.  We get:

(n - 6)(3n + 1) = 3n(n - 5), or

3n² + n - 18n - 6 = 3n² - 15n

Simpify by combining like terms.  3n² on the left is the same as 3n² on the right, so we cancel these terms:

n - 18n - 6 = - 15n.

Continuing to combine like terms, we get:

-2n = 6, so that n = -3.

Note that there is no problem subbing -3 for n in the given proportion; both fractions will be defined.  Thus, n = -3 is the solution desired.

sinn is the total amount of students now and m were the students before, you subtract them both (n-m) and divide that by m. then, since to get a percentage from a fraction you have to multiply by 100, your answer should look like this: n-m/m*100
