your equation is this 9N=63 9N/9=63/9 N=7 your answer is 7
45+4 = 49 49/7=7 7*7=49-4=45 so x=7
9n + n = 10n
n - 10 + 9n - 3 n + 9n - 10 - 3 10n - 13
If it is: 13m+5n-6m+9n Then simplified it is: 7m+14n
9n - 9 = 45 9n = 45 + 9 = 54 n = 54 / 9 = 6
-9n=45 negative nine times n equals forty-five you have to do it backwards n=45/-9 n equals forty-five divided by negative nine standard manipulation of terms give it try with some others you'll be amazed how much easier fractions are than decimals
you have 9n+17=-1 -17 -17 9n=-18 /9 /9 n= -2
its is 45 just kidding I do not know what it is
54 / 9 = n n = 6
The equation "9n equals 126" can be written as 9n = 126.
9n + 18 = 81 9n = 63 n = 7
-19 + 9 = -10n = -19n+9=-10-9 -9n=-19
9n+9=81 9n=72 n=8
12
it equals -4n
it equals -15
