42 decreased by twice Jenny's height
Use the variable j to represent Jenny's height.​

2j-42

Step-by-step explanation:

42 decreased means -42

twice Jenny's height(j) = 2j

Put this all together, you have 2j-42

Hope this Helps!

x = 42 - 2j

or

x = 42 - 2 ( j )

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)
