how do you solve for a variable ex: 2w=h+7*u solve for u?

Question

solving for a variable . put in layman term. 7th grade math

Answer 1

2w = h + 7u

2w - h = 7u

u = (2w - h)/7

Answer 2

"Solving for" is the same as isolating on one side of the equation. The way you do this is that by adding, subtracting, multiplying and dividing by the same quantity or expression on both side of the equation, you keep the equality.

So, in this case, you want to isolate u.

To do this, you first want to get all terms that don't have a "u" in them to one side of the equation. In this case, that means getting the h to the left side. To do that, subtract both sides of the equation by h

Now, the equation looks like: 2w-h=h-h+7u or 2w-h=7u

Now, you want to get the u by itself. That means you have to somehow turn the coefficient in front of the u into a 1. To do this, divide both sides of the equation by 7. Now, you get:

(2w-h)/7=7u/7

Since 7/7 = 1, you get (2w-h)/7=u

Answer 3

2w = h + 7 * u

Divide both sides by h + 7 -:

2w / h + 7 = u (h + 7) / (h + 7)

We can cancel the h + 7 on the left side-:

2 w / h + 7 = u

Answer 4

you're looking to have u = something

in order to do this, remember what you do to one side of the = sign has to be done to the other...

let's -h from both sides...

2w - h = h-h+7*u

2w - h=0 + 7*u

2w - h = 7*u

now, we need to divide both sides by 7 to get u by itself

(2w - h)/7 = (7u)/7

(2w - h)/7 = 1u

(2w - h)/7 = u

TADA

Answer 5

2w=h+7*u

Subtract h from each side

2w-h=7*u

Now divide u by each side

(2w-h)/7=u

Answer 6

7u + h = 2w
7u = 2w - h
u = (2w - h) / 7

Answer 7

(2w – h)/7=U
