5n + 7 = -41 5n = -48 n = -48/5 n = -9.6
5n+15 = 25 5n = 25-15 5n = 10 n = 2
5n+4=0 5n=-4 n= -4/5
5n - n = 8 + 4 ie 4n = 12 so n = 3
-5n - (-2) = 27 -5n + 2 = 27 -5n + 2 - 2 = 27 - 2 -5n = 25 -5n/-5 = 25/-5 n = -5
5n-25 = 10 5n = 10+25 5n = 35 n = 7
5n + 7 = -41 5n = -48 n = -48/5 n = -9.6
If 5n + 8 = 43, then n = 7
5n+15 = 25 5n = 25-15 5n = 10 n = 2
Could be anything! We'd have to know the final sum to figure out what "N" would be, like 5N +N = 24.
The GCF is n.
30
5n+4 = -26 5n = -26-4 5n = -30 n = -6
5n if n = 7 is 5 x 7, or 35.
9 - 5n + 1 = 15 -5n = 15 - 10 n = -5/5 n = -1
5n+4=0 5n=-4 n= -4/5
5n - n = 8 + 4 ie 4n = 12 so n = 3
