How to solve 7 + 13n - 1 > 5 ( 2n + 2 ) + 8 by two step inequality

n>4

Step-by-step explanation:

1. Let's first simplify each sides.

7 + 13n − 1 > 5(2n+2) + 8

a. 7 - 1

Distribute the 5.

b. 5 x 2n = 10n

   5 x 2 = 10

c. 10n + 10 + 8 = 10n + 18

13n + 6 > 10n + 18

2. Now, eliminate 10n on both sides, as there can't be 2 variables on the opposite sides.

13n  + 6 > 10n + 18

-10n        -10n

a. 3n + 6 > 18

3. Subtract 6 from each side.

3n + 6 > 18

     -6     -6

a. 3n > 18

Divide 3

b. n > 4

Sorry for the long explanation, but i hope this helps!

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)

the answer is c just got it on ed
