n - 10 + 9n - 3 n + 9n - 10 - 3 10n - 13
n-10+(9n-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
it is 10n
do it yourself

n2 + 9n + 18 = (n + 6)(n + 3)
9n + n = 10n
9n + 4 = 31 (given)9n = 27 (subtract 4 from both sides)n = 3 (divide both sides by 9)
9n+9=81 9n=72 n=8
