For n+9=18, the answer would be n=9 because n+9=18 also mean 18-9=n so 18-9=9
n + 26 = 41 n = 41 - 26 n = 15 Thanks
Subtract 2n from each side: 3n - 9 = 6 Add 9 to each side: 3n = 15 Divide both sides by 3: n = 5 Therefore, n = 5
your expression is this... n+5=3+12 n+5=15 n=10
2 plus n is the true one, but 1 plus n is not?
If you know that n = 15, substitute 15 for n and solve: n + 3 - 9 15 + 3 - 9 9
It is an equation and the value of n is 6
15 + n = 24 (subtract 15 from both sides) n = 9
n=6
15 - n when n equals 9 = 6
9 - 5n + 1 = 15 -5n = 15 - 10 n = -5/5 n = -1
n = 8
3n = 15 + 12 = 27, 27/3 = 9 = n
9
24
n X .15 = 9 9 / .15 = n 9 / .15 = 60
3 + 9 = 12
