Which system of equations is equivalent to the following system? 2x + 4y = 14 4x + y = 20 2x + 4y = 14 −16x − 4y = −80 2x + 4y = 14 −4x + y = −20 4x + 8y = −28 4x + y = 20 −2x − 4y = 14 4x + y = 20

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)

i think da answer is

d.square root of 3
