Solve the equation below. If the solution is not an integer, give it in fractional form reduced to lowest terms. X-9 over 4 =3

x = 21

eliminate the denominator of 4

you can do this buy multiplying both sides by 4

x -9 = 12

x = 21

b. astronomers

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)
