5n-2+2=4n 5n=4n n=0

it equals -4n

3n + 2n = 7 + 4n 5n = 7 + 4n 5n - 4n = 7 n = 7

4n

N=3.

1

In the equation 5n-11=4n+20, n is equal to 31.

5n - n = 8 + 4 ie 4n = 12 so n = 3

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

-2n

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

The GCF is n.

4n - 5n is biger and no it not

5n + 15 = 25 you subtract 15 from both sides then you get 10 then divided 5n by 10 you get 2n

-3n+5n+4 = -4 2n = -4-4 2n = -8 n = -4

It is: 4n-13

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

5n-25 = 10 5n = 10+25 5n = 35 n = 7

Whatever your value of n is, you need to multiply it by 5 and then add 2 to get your answer. Below is how to solve it algebraically: 5n+2 = 0 (it needs to be equal to something in order to solve it, so I assumed that it equals zero) 5n = -2 n = -2/5

6n

It is: 16n

-4n3 + 8n2 - 4n + 7

5n+4 = -26 5n = -26-4 5n = -30 n = -6

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