Question

A=8h
solve for h
I don't understand how to do this. Please help?

Answer 1

`h = (A)/(8)`

Explanation:

The equation you are given is solved for A. A is alone on one side. You want the equation solved for h. You want h alone on the left side, and what h is equal to on the right side. You want to isolate h.

A = 8h

Since you want h alone on the left side, and there is an h only on the right side, we start by switching sides.

8h = A

Now you have h on the left side. h is being multiplied by 8. The opposite operation to multiplication is division. To undo the multiplication by 8, you need to divide by 8. The rule with equations is that you must do the same operation to both sides of the equation. We now divide both sides of the equation by 8.

`(8h)/(8) = (A)/(8)`

The left side simplifies to just h, which is what we want.

`h = (A)/(8)`

Answer 2

h = A/8

Explanation:

To isolate h you divide both sides of the equation by 8:-

A/8 = 8h/8

A/8 = h
