5n-2+2=4n 5n=4n n=0
8n-2+4n = 66-5n 8n+4n+5n = 66+2 17n = 68 n = 4
1
In the equation 5n-11=4n+20, n is equal to 31.
5n - n = 8 + 4 ie 4n = 12 so n = 3
5n-2+2=4n 5n=4n n=0
it equals -4n
3n + 2n = 7 + 4n 5n = 7 + 4n 5n - 4n = 7 n = 7
4n
8n-2+4n = 66-5n 8n+4n+5n = 66+2 17n = 68 n = 4

In the equation 5n-11=4n+20, n is equal to 31.
5n - n = 8 + 4 ie 4n = 12 so n = 3
-2n
5n+4 = -26 5n = -26-4 5n = -30 n = -6
5n=30n=30/5n=6
4n + 1 = 12 + 5n First, let's get all n terms on one side and all non-n terms on the other side. Start off by subtracting 4n from each side. 1 = 12 + n Now subtract 12 from each side. -11 = n
