10n = 7n + 4 + 2n so 10n = 9n + 4 Subtract 9n from both sides: n = 4

The equation N-10 plus 9N-e equals 10N-3. This is a math problem.
9n + 18 = 81 9n = 63 n = 7
it is 10n
10n = 7n + 4 + 2n so 10n = 9n + 4 Subtract 9n from both sides: n = 4
-26
The equation N-10 plus 9N-e equals 10N-3. This is a math problem.
9n + n = 10n
n-10+(9n-3)=10n-13
-19 + 9 = -10n = -19n+9=-10-9 -9n=-19
n - 10 + 9n - 3 = 10n - 13
n - 10 + 9n - 3 n + 9n - 10 - 3 10n - 13
9n + 18 = 81 9n = 63 n = 7
it is 10n
it equals -4n
9n+9=81 9n=72 n=8
