You need to get n alone.9n=45 → Divide by 9n=45/9n=5
4n2-25 = 0 4n2=25 n2=6.25 n=sqrt(6.25) n= +2.5 or -2.5
3n -5 = 19 3n = 19+5 3n = 24 n = 8

The answer is n = 5.
n - 6m = 8 n = 6m + 8
N=l-m
54 / 9 = n n = 6
(n-2)x180
If n + 7 = 12, then n = 12 - 7
sqrt(n) = S*r2sqrt(n)/S = r2 sqrt(sqrt(n)/S) = ror4th root of n/sqrt(S) = r.If your equation was sqrt(n) = S*r-2sqrt(n) = S*(1/r2)sqrt(n)/S = 1/r2S/sqrt(n) = r2 sqrt(S/sqrt[n]) = rorsqrt(S)/4th root of n = r

n - 15 = 86n = 86 + 15n = 101
