Simplify this expression. 13h - 7 - 2h - 4

11h - 11

Step-by-step explanation:

13h - 7 - 2h - 4

combine like terms:  13h + (-2h) = 11h

11h -7 -4

combine like terms again:  -7 + (-4) = -11

11h - 11

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)
