3c+6=18
3c+6-6=18-6
3c=12
3c÷3=12÷3
c=4
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
few errors in your title: 2 plus 4 = 6 6 plus 9 = 15 10 plus 25 = 35 18 + 81 = 99
(4*18)+6 = 78
n + 6 = 18 n = 12

9x+6 = 7x+18 9x-7x = 18-6 2x = 12 x = 6

-18
3n+6=18 n+2=6 n=4
3 times 6 is 18 2 times 5 is 10 18 plus 10 is 28
b = -8
a + 18 = 7a a-a +18 = 7a-a 18 = 6a 18/6 = 6a/6 3 = a 3=a
No. -18 / 3 = -6
4x+6-7x+9=18-3x+15=18-3x=3x=-1
x=4
do you mean what is 3+6+9-12? The answer is 6: 3+6=9 9+9=18 18-12=6 :)
