Question

Rearrange the equation so w is the independent variable.

−2u+6w=9

Answer 1

Answer: u = -9/2 + 3w

Explanation:

Hi, An Independent Variable in an Equation is a variable that may have its value freely chosen without considering values of any other variable. Is also known as the input value of a function.

So, to rearrange we have to isolate u:

-2u+6w=9

-2u =9 -6w

2u = -9 +6w

u= (-9 +6w)/2

u = -9/2 + 3w

Feel free to ask for more if needed or if you did not understand something.

Answer 2

`u=3w-4.5`

Explanation:

we have

`-2u+6w=9`

Solve for u

That means ------> isolate the variable u (dependent variable)

Subtract 6w both sides

`-2u=9-6w`

Divide by -2 both sides

`u=(9-6w)/(-2)`

`u=3w-4.5`
