-3n+5n+4 = -4 2n = -4-4 2n = -8 n = -4
5n - n = 8 + 4 ie 4n = 12 so n = 3
If 5n + 8 = 43, then n = 7
-2n
It is: 8n(5n+8)
You're not really sure what you're looking for, are you.You're looking for the number that 'n' must be to make the statement true.Here's how to find it:8 = 5n + 4Subtract 4 from each side of the equation:4 = 5nDivide each side by 5:4/5 = n
8, 13, 18, 23, 28, etc.
N= -2 5 * -2 is -10 -10 +2 is -8
8n(5n+8)
33
-5n - 8 < 2(-n) - 83-5n - 8 < -2n - 83 (add 5n and 83 to both sides)-5n + 5n + 83 - 8 < -2n + 5n + 83 - 8375 < 3n (divide by 3 to both sides)25 < n orn > 25
