Answer: N =
Step-by-step explanation:
- So, we're trying to find a value of N, so we can use one of the equations, isolate x, and create a new equation to find a value that N can equal.
- It's up to you which one to choose, but I suggest isolating the fraction. X is equal to 1/70N. Now, plug that into the first equation, which should be 1/70N + N = 71/10.
N can also be written as 70/70N, because that's equal to 1 N, our current value of N.
71/70N = 71/10
. Find a value of N that makes the statement equivalent. In this case, N = 7 works.
