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
