5n - 4 = 10n + 6-5n = 10n = -2
5n+4=0 5n=-4 n= -4/5
6m + 5n - 4m + 7n = 2m + 12n
5n+15 = 25 5n = 25-15 5n = 10 n = 2
-5n+9=-46 -5n+9-9=-46-9 -5n=-55 -5n/-5=-55/-5 n=11
5m-5n+5m+5n When simplified: 10m
3n+5n=8n
6n + 5n is 11n.
4 over 5n
5n+4 = -26 5n = -26-4 5n = -30 n = -6
It is an algebra expression meaning: 5n+4
If 5n + 8 = 43, then n = 7
5n - 4 = 10n + 6-5n = 10n = -2
5n+4=0 5n=-4 n= -4/5
(2n+3)(n+1)=2n2+5n+3.
6m + 5n - 4m + 7n = 2m + 12n
5n+15 = 25 5n = 25-15 5n = 10 n = 2
