2*(15 + N)
if you mean 2n=8, then N=4, which translate to 2x4=8
n = number 2(n + 15) ======
2(7+5)=n 2(12)=n 24=n but its an opposite n, so the answer is -24
It is twice as great.
twice a number n is 2n plus 3 is + 3 → twice a number n plus 3 is 2n + 3.
3 less than twice n is 2n-3
If the number is n, then twice the number is 2n and the sum of the two is n + 2n = 3n.
Twice the number n is 2n.
11
n
Since n is positive, |n| = n, so you have 2n - n = n. The difference is n.
yes
2n+8
2(n - 11)
2*(15 + N)
15+2*n = 9 2*n = -6 n = -3
