The solution (not sum) to the equation 21 = 3c + 6 is as follows:21 = 3c + 621 - 6 = 3c + 6 - 615 = 3c3c = 153c/3 = 21/3c = 7
Equality
3n+6=18 n+2=6 n=4

8d = 5d+18 8d-5d = 18 3d = 18 d = 6
The solution (not sum) to the equation 21 = 3c + 6 is as follows:21 = 3c + 621 - 6 = 3c + 6 - 615 = 3c3c = 153c/3 = 21/3c = 7
If: 3c = 6Then: c = 2
18
Equality
18 + (-6) = 12
few errors in your title: 2 plus 4 = 6 6 plus 9 = 15 10 plus 25 = 35 18 + 81 = 99
n + 6 = 18 n = 12
(4*18)+6 = 78
