Answer:x=-4

Step-by-step explanation:

move 5x to the other side by cancelling it out with -5x

that causes it to be 6-6x=30

move 6 to other side by cancelling out with -6

causes it to be -6x=24

divide by -6 to get x alone

x=24/-6

answer is -4 when reduced

Answer: $x = (\frac{1}{4ab})^{2}$

Step-by-step explanation:

Given:

$4a\sqrt{x} = \frac{1}{b}$

To make $x$ the subject of the formula means that we want to make $x$ to stand alone , the first thing to do is to multiply through by 1/4a , that is

$\sqrt{x} = \frac{1}{4ab}$

take the square of both sides:

$x = (\frac{1}{4ab})^{2}$
