5n-25 = 10 5n = 10+25 5n = 35 n = 7
5n - 10 = 0 5n - 10 (+10) = 0 (+10) 5n (/5) = 10 (/5) n = 2
5n+15 = 25 5n = 25-15 5n = 10 n = 2
5n + 10 = 10 5n = 10 - 10 5n = 0 n = 0 taylor101119: well i thought it was 5*n+5*2=10 i thought n=1 but i'm pretty sure it's the one ontop^
9 - 5n + 1 = 15 -5n = 15 - 10 n = -5/5 n = -1
5/(n - 12) = 10(n + 5) (multiply by the common denominator (n - 120(n + 9) to both sides)[5/(n - 12)][(n - 12)(n + 9)] = [10(n + 5)][(n - 120)(n + 9)] (simplify)5(n + 9) = 10(n - 12)5n + 45 = 10n - 120 (subtract 5n and add 120 to both sides)5n - 5n + 120 + 45 = 10n - 5n + 120 - 120165 = 5n (divide by 5 to both sides)33 = n
5n + 15 = 25 you subtract 15 from both sides then you get 10 then divided 5n by 10 you get 2n
5(n - 2)
f(n)=15n2+5n
5n + 7 = -41 5n = -48 n = -48/5 n = -9.6
If 5n + 8 = 43, then n = 7
Could be anything! We'd have to know the final sum to figure out what "N" would be, like 5N +N = 24.
