2n + 8 = -142n = -22n = -11
If 'n' is 8, then (2n - 7) is 9 .
2(4) = 8
2n+2n equals 4n
if you mean 2n=8, then N=4, which translate to 2x4=8
Nonsense.
2n plus 7 equals 19 2n equals 12 n equals 6
If n = 4, then 2n = 8 25 + 8 = 33 25 - 8 = 17 25 x 8 = 200 25/8 = 3.125
If n = 9 then 2n must be 18.
If En = 2n then E9 = 2*9 = 18
+×= Therefore we have n/8 - 2n/3 Find the LCM of 8 & 3 which gives us 24 (N÷8 - 2n÷3)/24 (3n-16n)/24 -13n/24
Un = 2n - 8 Un = 2n - 8 Un = 2n - 8 Un = 2n - 8
