how to solve
4/n+2 = 7/n

Answer 1

Cross multiply.

a/b = c/d
Becomes
a x d= b x c

Answer 2

So
4 x n = (n+2) 7

Answer 3

Distribute the right side
(n+2)7
=n(7) + 2(7)
= 7n+14

Answer 4

So
4n= 7n+14

And try to solve for n from here...

Answer 5

i can't find n

Answer 6

-3n=14
Divide both sides by -3

n=14/-3
