Question

5pn-8p=7n-7. Solve for n.

Answer 1

Answer:

       -8p + 7

n = --------------

        8 - 5p

Step-by-step explanation:

Let's group the n terms in  5pn-8p=7n-7  .

Subtract 5pn from both sides.  This results in -8p = 7n - 7 - 5pn

Now add 7 to both sides.  This will group the n terms on the right side:

-8p + 7 = 7n - 5pn

Factor n out of 7n - 5pn:

-8p + 7 = n(7 - 5p)

Finally, divide both sides by (7 - 5n) to isolate n:

       -8p + 7

n = --------------

        8 - 5p
