n + 13 = 21. n = 21 - 13
n=3
n + (2 x 3) = 21 Therefore, n = 21 - (2 x 3) n = 15
38+n=57 n=57-38 n=19
n + 15 = 36 Therefore, n = 36 - 15 n = 21
2n plus 7 equals 19 2n equals 12 n equals 6
n=10
n + 13 = 21. n = 21 - 13
n=3
n + (2 x 3) = 21 Therefore, n = 21 - (2 x 3) n = 15
38+n=57 n=57-38 n=19
n + 15 = 36 Therefore, n = 36 - 15 n = 21
If 27+n = 46 then the value of n = 19.
-19 + 9 = -10n = -19n+9=-10-9 -9n=-19
38 + (n/2) = 21 Therefore, n/2 = -17 n = -17 x 2 n = -34
2n + 19 = -7 2n = -7 - 19 2n = -26 n= -13
