Question

Rearrange the equation so U is the independent variable. 4u+8w=−3u+2w

Answer 1

independent variable means the variable after the equal sign

Answer 2

`u=-(6)/(7) w`

Explanation:

`4u+8w=-3u+2w`

Add
`3u` and
`-8w` on both sides.

`4u+3u=2w-8w`

Add or subtract like terms.

`7u=-6w`

Divide
`7` on both sides.

`7u/7=-6w/7`

`u=-(6)/(7) w`

`u` is the independent variable now.
