10n+12 = 14n-12 10n-14 = -12-12 -4n = -24 n = 6
2n plus 7 equals 19 2n equals 12 n equals 6
-24
your expression is this... n+5=3+12 n+5=15 n=10
n + 8 = 12Subtract 8 from each side:n = 4
10n+12 = 14n-12 10n-14 = -12-12 -4n = -24 n = 6
If n + 7 = 12, then n = 12 - 7
N=0.
2n plus 7 equals 19 2n equals 12 n equals 6
n=22 22 +12 34
15 + n = 24 (subtract 15 from both sides) n = 9
It is a linear equation in one variable, n.
12+123456789=123456801
n + 6 = 18 n = 12
So, 3 + 12 = n + 3. Subtract 3 from both sides of the equation and get 12 = n or n = 12 if you prefer.
3 + 9 = 12
