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?
