Question

Rearrange the equation so u is the independent variable.

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

Answer 1

I'm not sure what you need...but here are two possible answers...

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

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

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

7u = -6w

u = -6w/7

OR

w = 7u/-6

Answer 2

Explanation:

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

8w-2w= -7u+2w-2w

6w= -5u

w= (-5u/6)
