N = x + y - n = 5<br> and part two<br> x = u + v = o<br><br> whats the answer?

Colt1911 [192]

Just substitute the value of x from second equation into first equation:
N = x + y - n = 5
N = u + v + y - n = 5
N = 0 + y - n = 5

In short, N would be equal to y - n which is still equal to 5

Hope this helps!
