Three more than twice a number.
Solve for n. 2n+3=0 2n=-3 n=-3/2
2n + 3 = 352n = 35 -32n = 32n = 32/2n = 16
3 + 3n = 9 + 2n + 4n n = -2
18n + 27 or 9(2n + 3)
twice a number n is 2n plus 3 is + 3 → twice a number n plus 3 is 2n + 3.
5n + 1 = 10 + 2n5n - 2n + 1 - 1 = 10 - 1 + 2n - 2n3n = 93n/3 = 9/3n = 3
6n -3=2n+9 6n-2n=9+3 4n=12 n=12/4 n=3
3n + 9 = 3(n + 3)
2n + 4m - 2n + m = 5m
If you mean: (2n-14)(3n+9) = 0 then it is a quadratic equation whose solution is n = -3 or n = 7
-2n
2n plus 4 = 2n + 4
