5/9v+w=2 solve for v

Question

jack1 · Answer

2 variables, one equation, you can only solve for v in terms of w

anonymous · Answer

from my son's 9th grade math book

anonymous · Answer

$$5\frac{9}{v}+w=2$$
or$$5\frac{9}{v+w}=2$$

which one is the problem

anonymous · Answer

top

anonymous · Answer

solving for v means you want v on one side... since lets get rid of the w on the left side since we want v on the left side. subtract w to both sides

anonymous · Answer

nope... 5/9 v+w=2

anonymous · Answer

yes -w on the left

anonymous · Answer

$$
\frac 5 9 v+w = 2
$$

anonymous · Answer

5/(9(2-w))=v

anonymous · Answer

1st subtract w so you get 5/9v = 2-w
2nd multiply v on both sides getting 5/9 = v(2-w)
3rd divide both sides by 2-w getting 5/(18-9w) = v

Thanks Propulsion

Don't cheat.  There is no point.  If the kid doesn't get it, get them a tutor.
