9n+9=81 9n=72 n=8
4n - 5n is biger and no it not
The equation "9n equals 126" can be written as 9n = 126.
9n + 18 = 81 9n = 63 n = 7
9n - 9 = 45 9n = 45 + 9 = 54 n = 54 / 9 = 6
9n+9=81 9n=72 n=8
4n - 5n is biger and no it not
6(n+12) + 3(n+6) = 58.5 6n + 72 + 3n + 18 = 58.5 9n + 90 = 58.5 9n = 58.5 - 90 9n = -31.5 n = -3.5
You need to get n alone.9n=45 → Divide by 9n=45/9n=5
The equation "9n equals 126" can be written as 9n = 126.
9n + 18 = 81 9n = 63 n = 7
8m + (4n - 6m) + 9n =8m + 4n - 6m + 9n =(8m - 6m) + (4n + 9n) =2m + 13n
9n + n = 10n
-5 plus 9n plus 6 is 1 plus 9n.
9n - 9 = 45 9n = 45 + 9 = 54 n = 54 / 9 = 6
Solve 5n+4n+32: Simplify the expression. 4n+5n+32=0; 9n+32=0 Group all constants on the right side of the equation. 9n+32=0; 9n+32-32=0-32; 9n=0-32; 9n=-32 Isolate the n. 9n=-32; 9n/9=-32/9; n=-32/9
9n is older then 8n
