Answer:
N = 20
Step-by-step explanation:
Move all terms to the left
35n/35-(700/35)=0
Add all of the numbers together, and all of the variables
35n/35-20=0
Multiply all of the terms by the denominator
35n-20*35=0
Add all of the numbers together, and all of the variables
35n-700=0
Move all of the terms containing N to the left, all other terms to the right
35n=700
n=700/35
n=20
