n - 10 + 9n - 3 n + 9n - 10 - 3 10n - 13
9n + n = 10n
10(N+14)=9N 10N+140=9N N=-140 I can verbalize this, I hope you can. Check 10(-140+14)=9(-140) 10(-126)=-1260 -1260=-1260
You need to get n alone.9n=45 → Divide by 9n=45/9n=5
your equation is this 9N=63 9N/9=63/9 N=7 your answer is 7
n - 10 + 9n - 3 n + 9n - 10 - 3 10n - 13
n - 10 + 9n - 3 = 10n - 13
The equation N-10 plus 9N-e equals 10N-3. This is a math problem.
-26
9n + n = 10n
-26
it is 10n
do it yourself
9n+9=81 9n=72 n=8
Strangely enough, it is 9n + 1 for n = 1, 2, 3, ...
9n + 4 = 31 (given)9n = 27 (subtract 4 from both sides)n = 3 (divide both sides by 9)
9n + 18 = 81 9n = 63 n = 7
