It won’t let me answer questions I don’t know why

This is because they are already answered. This has happened to me to but don't worry. You can also comment if it makes you feel better. I also comment questions because i just want to help people. If the answer button is available I will attempt to answer.

Hopefully this helps!

P.S. The Wi-Fi problem with an error means that you have to refresh, shut down, restart, connect Wi-Fi or try to close the tab and open it again.

welp you either gots eh banned for doing dumm stuff or they already answered it for you...

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)

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9
