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

The GCF is n.

4n - 5n is biger and no it not

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

It is: 4n-13

(4n - 1)(3n + 2)

6n

It is: 16n

4 = 5n + 6n2 is a quadratic equation.

5n+6=(-4) n= (-2)

5n+4=0 5n=-4 n= -4/5

5n - 4 = 10n + 6-5n = 10n = -2
